Nowadays, optical coherence tomography (OCT) in medical diagnostics is considered a prominent imaging technique that can give high resolution, cross- sectional and threedimensional images of bio- medical tissues in real time, using the coherence properties of laser light [23]. • The analysis of human clinical specimens (e.g. The scope of Physics in Medicine consists of the application of theoretical and practical physics to medicine, physiology and biology. This sharp metal tip is placed in the focus of a laser beam and hence an effect called “local field enhancement” will cause the electric field to become roughly 1000 times stronger. Second, I will remind you of an enormously important phase in the history of biology in which physicists transformed the study of living things by helping to discover … • It is a minimally invasive technique, since a small sized sample can lead to good results. The imaging techniques cover advanced optical imaging and spectroscopy, nuclear imaging with radioactive tracers, magnetic resonance imaging, ultrasound and optical and X-ray imaging. In this review article, some of these impacts and developments will be discussed within the framework of the research conducted at the Laboratory of Lasers and New Materials (LLNM) of Cairo University and which encompass: • Laser Induced Breakdown Spectroscopy in medical sciences and applications. Although this field is still in its infant stage, there is a growing interest among the medical community for the medical applications of nanomaterials and nanotechnology due to its ability to bring more progress and breakthroughs in diagnostics, treatments and prevention of diseases [79]. Together with his colleagues, he has shown that gold nanoparticles can enhance the efficacy of low-energy X-rays in irradiated cells [90]. These huge and high energy lasers produce large amount of heat and have to be cooled after every pulse, and for that reason they are not suitable as pumping sources for X- ray lasers in medical applications. Among the highlights in materials science and nanotechnology is the discovery of graphene in 2004 by the eminent physicists Andre Geim and Konstantin Novoselov at Manchester University (UK). The distillation technique of zinc production goes back to the 12th Century AD and is an important contribution of India to the world of science. LIBS- based identification of bacteria is also applied to non-clinical industrial applications. Impact of Physics on Medical Sciences and Applications: Lasers and Nanotechnology. The main function of the biosensor is to sense a biological specific material such as antibodies, proteins, enzymes, immunological molecules etc. IPEM's aim is to promote the advancement of physics and engineering applied to medicine and biology for the public benefit. In the medical community, interest grows as laser physics is developing ways to expand the optical range of lasers to the shorter wavelength regions, i.e. A technique that employs nanoparticles to deliver drugs to specific types of cells is currently under development, with some applications already being used. Lieber group at Harvard University has developed a complex one dimensional architecture comprising at least 200 independent electrical nanowire assemblies that has been used to perform a low level detection of serum- bone cancer antigens. These applications include the detection of glucose in diabetic patients the detection of urinary tract bacterial infections the detection of HIV-AIDS and the diagnosis of cancer [103-109]. Medical physicists from the University of Puerto Rico (USA), experimentally demonstrated how quantum dots are an ideal “mediator” in such multimodality regimes [94]. It has recently been used in various medical applications, which include biosensing, medical imaging, drug delivery, and cancer therapies [131-133]. It could therefore be used for chemical sensing and detection of single molecules. Your email address will not be published. Doxorubicin (DOX) is embedded onto the graphene sheet, while the molecules of tumor necrosis factor-related apoptosis– inducing ligand (TRAIL) are linked to nanostructure via short peptide chains (Figure 5).

This imaging technique has the ability of achieving sub- micrometer resolution over a wide range of wavelengths, 100 nm, together with the advantage of high signal-to-noise ratio, permitting fast signal acquisition. There are several other research groups that have also paid attention to the graphene-based drug loading and delivery systems and a number of interesting results have been published [159,160]. Its impact onthe advances in the medical field is considerable through its many promising applications in the area of cancer treatment, the treatment of infectious, cardiovascular, neurological, lung and blood diseases, diabetes and dentistry. Other nuclear constructs appear useful for monitoring transfection events by imaging proteins that are expressed after reporter gene transcription. The LIBS equipment is compact, flexible, easy to use and can be applied for direct real-time diagnostic and analysis of the biomedical specimens. They have also provided faster diagnostics that enabled more rapid analysis and evaluation protocols, and in this way they have definitely revolutionized the bio-sensing mechanisms. Injected intravenously, the graphene strips with the drug playload preferentially concentrate to the cancer cells due to common blood vessel leakage around the tumor. You could then go on to specialise in medical physics. AuroShell is currently being tested in a phase I clinical trial for head and neck cancers. in different parts of bone, in joints or in different regions of the liver). What is physics? Fan and and his research group reported a graphene oxide-based multicolor DNA probe for rapid, sensitive and selective detection of DNA targets in solutions. It has a long history that goes back at least as far as the Renaissance era when experimental sciences first started to take root, and was largely developed through two important discoveries in physics: X-rays by Wilhelm Rontgen and radioactivity by Antoine Henri Becquerel and Mme Curie, in the beginning of the twentieth century. Moreover, there are numerous clinical applications that are concerned with the use of nanobiosensors in routine. Nanotechnology has the potential of yielding considerable progress in medical diagnostics, with the ultimate goal of identifying diseases at the earliest stage possible (even up tothe level of a single cell). Recently, LIBS has been applied to biological and medical systems, and extensively in the analysis of human tissue samples. Nanomaterials are indispensable incumbents in this dimension as they have high surface area to volume ratios which allow the surface to be used in a better and far more diversely functional manner [99]. After the demonstrations of X-ray lasing from plasmas of neon-like ions of selenium and nickel-like ions of palladium, extensive work - both theoretical and experimental was carried out by physicists in different research laboratories in order to investigate the possibilities to produce X-ray lasing from other atomic transition mechanisms [41-43]. XXX. Imaging depth is usually about 1 mm, but is dependent on the specific properties of the tissues [30]. LIBS application as a diagnostic technique that can rapidly detect and identify pathogenic microorganism is therefore of utmost interest to the medical community. kidney and gall bladder stones). He carried out multi-configuration Hartree- Fock (MCHF) calculations for singly ionized krypton in order to determine the lifetimes of laser levels in this ion. Many more anticancer nanomedicines are under clinical development, of which some are based on very different principles than chemotherapy. A super-resolution imaging method based on the sequential localization of photo-switchable fluorescent probes has recently been invented [123,124]. But there is a lot of overlap between these … Infrared light from a laser was absorbed by the nanotubes and produced heat that incinerated the tumor [91,92]. This medical imaging technique is based on low- coherence interferometry, typically employing near- infrared light. As we look to the future, the tables will be turned somewhat. Cui and Lieber have reported the performance of biosensors based on silicon nanowires doped with boron and used them for the detection of biological and chemical species [101]. This should allow drugs that must now be delivered as an injection, to be taken in pill form. A biosensor is an analytical device used for the detection of an analyte, that combines a biological component with a physiochemical detector [96,97]. • It gives online quantification for all trace elements in a tissue simultaneously. Most of the heavy members of the iso-electronic sequences studied radiate in the soft X-ray spectral region with wave lengths between 5 and 50 nm. The intracellular acidic environmental promotes DOX’s release from graphene. Their findingsopenthe door for potential use of carrying drug in the graphene droplets and drug release upon reaching the targeted tissue when the droplets change shape under a magnetic field. For some (CT) exams, an intravenous contrast injection is required to enhance visibility in the area of the body being examined. The term nanotechnology was first envisioned by the distinguished physicist Richard Feynman in his illuminating lecture entitled “There is plenty of room at the bottom”, that he gave in 1959 at the California Institute of Technology. It has several and diverse applications in medical diagnostics, such as in ophthalmology and optometry where it can be used to obtain detailed images from within the retina [24,25]. "Mental health in Islamic medical tradition". Soon after the advent of lasers in 1960 they found their way into biomedical sciences and medical applications, such as ophthalmology, dermatology, cosmetic surgery, oncology, dentistry and many areas of medicine [31-36]. The identification of the different elements was carried out using a spam 16 software spectrum analyzer. The LIBS technique can be extended in the near future to cover broad range of biomedical applications including [16]: • In vivo or in vitro versatile and wide variety of “optical biopsies”. By convention, nanotechnology is taken as the scale range 1 to 100 nm, following the definition used by the National Nanotechnology Initiative in the US, where the sizes of most atoms and molecules of medical interest lie within this range. The exponential growth of biocompatible nanotechnology now promises to expand the horizon for molecular imaging and therapy with a host of new agents. They developed the method of laser chirped- pulse amplification, where a very short pulse is expanded before it travels through the amplifier and then compresses to its original duration before the laser beam is focused on the target [40]. CS1 maint: ref=harv By loading the particles with chemotherapy drugs–established cancer killers–one can deliver the drugs to tumor cells without damaging healthy cells. Moreover, their electrochemical properties are the important assets for the biosensor technology. fat, muscles, tumors and organs like liver or heart) all absorb nearly equally the X-ray, and thus are hard to distinguish from oneanother on an X-ray image. In this paper, a general survey has been made of physics applications in medicine. As scientists discovered more and more about the cosmos using physics, they were able to provide verifiable and testable answers to … Wang have used optical fibers with nano-size diameters and coated with antibodies to detect the presence of toxicants within the single cell [102]. bacteria, moulds, yeasts and viruses). Graphene nanopore sequencing provides very inexpensive and rapid DNA sequencing and has potential to boostpersonalized health care. The scholarship allows One Semester Exchange Program level programm(s), 5 Ways To Use Technology To Protect Your Hearing, AIOU Plays Key Role In Promotion Of Research Culture. And what is medical imaging? They also extended the applications of LIBS technique for in- situ study of deciduous tooth and in vivo study of human nail. Once X-ray lasers become reliable, efficient and economical, they will have several important applications in medicine and biomedical sciences. Inbiosensing several researches utilized the strongly binding energy of nucleotide basesin DNA to graphene surface on the one hand, with the effective fluorescence-quenching ability of grapheme on the other hand, to develop novel graphene-based DNA detection platforms [140-142]. Physics describes how the natural world works through applied mathematical formulas. These spikes correspond to drops in conductance when DNA strands slide across the pore via a biochemical process known as translocation (Figure 4). Biochemical processes help explain the complexity of life by controlling the flow of information and biochemical signaling and flow of information. Pakistan's Newspaper on Science, Technology, Engineering, Innovation. Physics is the branch of science which deals with matter and its relation to energy. In 2013 they demonstrated how to tailor the hydrophobicity of graphene for its use as nanopores for DNA translocation and it was shown that single-stranded DNA could be detected in graphene nanopores with excellent nanoporedurability and reproducibility [135]. • It is capable of detecting trace elements with very low concentrations in the range of one part per million. Assuming that light emitted is sufficiently influenced by the characteristic parameters of the plasma, the atomic spectroscopicanalysis of the emitted light shows considerable information about the elemental structure and the basic physical processes in plasmas [4]. The in vivo behaviors of NGO-PEG were investigated in several different xenograft tumor mouse models, showing remarkably high passive uptake of graphene in tumors [161]. The goal is to create highly sensitive and reliable detection agents that can also deliver and monitor therapy. Without the bulky (TRAIL), the graphene strips with the embedded (DOX) are swallowed into the cells. Max Planck, German theoretical physicist who originated quantum theory, which won him the Nobel Prize for Physics in 1918. Moreover, the ability to incorporate drugs or gens into detectable site-targeted nano-systems represents a new paradigm in therapeutics that could usher in an era of image-based drug delivery and dosing [112]. In drug delivery and cancer therapy, graphene was first explored and investigated by the group of Hogji Dai at Stanford University (USA) in 2008 [132,158]. (2ndedn),Pub Blackwell. Medical physics is the application of physics principles to medicine or health care. In the medical applications and diagnostics nanomaterials are playing an important role in the development of efficient biosensors which can analyze the minute details of biological interactions with extreme precision and sensitivity [100]. Aromatic anti-cancer drugs (e.g. Laser Induced Breakdown Spectroscopy (LIBS) is a form of optical emission spectroscopy [1-3]. It is well known that tumors stimulate the growth of new blood vessels in their neighborhoods that can supply them with oxygen and other nutrients to sustain their rapid cell replication and growth [87]. Technology Times Web team handles all matters relevant to website posting and management. Further developments in computed tomography were the invention of optical coherence tomography (OCT) that uses light to capture micrometer resolution, three- dimensional images from within optical scattering biological tissues [23]. The investigations revealed salient enhanced spectral emission from the nanoparticle targets of the compounds to that from their bulky counterparts [168]. This additional control in the time domain allows molecules with spatially overlapping images to be separated in time, and consequently allows their positions to be precisely determined. Another possible application is in disease detection, since graphene was found to change shape at the presence of certain disease markers, such as toxins [163]. Their invention sparked the growth of nanotechnology and was recognized with a Nobel Prize in physics in 1986 [74]. Originating from the Greek word for “dwarf” (nános), “nano” describes physical length scales that are in the order of a millionth of a millimeter. They have more and large gaps in their walls than healthy blood vessels. His work was further developed by the atomic physics group at the Laboratory of Lasers and New Materials (LLNM) at Cairo University, in order to study the possibility of laser emission from excited electrons in atomic iso-electronic sequences. Laboratory of Lasers and New Materials (LLNM), Physics Department, Faculty of Science, Cairo University, Giza, Egypt, Received: February 20, 2016 Accepted: March 02, 2016 Published: March 08, 2016. The excited neon-like selenium ions in the plasma emit a coherent soft X-ray beam from the 3p–3s transition with a wavelength of 21 nm (Figure 2). The review article discusses the impact of physics in medical fields in so far as it is related to the research conducted at the Laboratory of Lasers and New Materials (LLNM) of Cairo University. In the application of liposomes as drug carriers, the localized release of their content (such as cytotoxic agents) is stimulated through exposure to ultrasound, heat or change in pH. The study reveals the higher occurrence of gallstones in female patients. Medical physics departments may be found in hospitals or universities. Afterwards, another group further showed that nano-graphene was significantly better than carbon nanotubes in inducing photothermal death of U251 human glioma cells in vitro [133]. Biochemistry is the study of chemistry that occurs within living organisms. TRAIL in the cell surface triggers the apoptosis while (DOX) attacks the nucleus. The X-ray (CT) imaging is similar to that taken by a planar camera, however, with two additional features. It is currently used to identify pathogenic bacteria, specifically for clinical applications in hospital microbiology laboratories or military field hospitals. In the mean time, research teams from the department of physics at Harvard University and the MIT have demonstrated that graphene can act as an artificial membrane separating two liquid reservoirs [138]. Figure 4: Artistic rendering of a DNA molecule traversing through a small whole (gap) made in an atomic layer of graphene that is located on a Si/S (coutesy: Cees D, Lab TU Delfet/Terr). The International Medical Journal. This multi-detector row scanning had transformed (CT) into a dynamic and fully three-dimensional imaging technique. To understand how a disease affects the organism, it is necessary to unde… In the nineties of last century and the beginning of this century, biomedical optical imaging witnessed breakthroughs in the development of imaging techniques, with the invention of the Scanning Near-Field Optical Microscopy (SNOM) and the Stochastic Optical Reconstruction Microscopy (STORM). Considered one of the most remarkable feats in metallurgy, the first seamless celestial globe was made in Kashmir by Ali Kashmiri ibn Luqman in the reign of the Emperor Akbar. Targeted perfluorocarbon nanoparticles were the first reported molecular imaging agent for ultrasound applications and were shown to increase reflectivity from fibrin thrombi in-vivo by two orders of magnitude or more [115-117]. Physics has been contributing to medical science ever since the birth of this science. The nanotechnology could play an effective role in radiation oncology. In 1998, (CT) was revolutionized with the introduction of the first four-slice spiral (CT) scanners. By applying a voltage of 200 mV across the graphene membrane, which channeled the flow of ions through the pore and registered as an electrical current signal, a series of spikes were observed in the electric current that scales the pore. The advances in laser physics have also considerable impact on medicine and biomedical research. • In vivo identification of ulcerated tissues. For example, CT together with the development of appropriate computer algorithms, made it possible to locate micro calcifications in digitized mammograms, which led to the early detection of breast cancer. However, for male patients they found that it is more prevalent for those who were having the habit of tobacco, chewing, smoking or drinking alcohols. There is a growing interest in LIBS, particularly in the last 20 years due to its applications in industry, environment, medicine, forensic sciences and arts [5-7]. I will discuss the effects of physics on the medical sciences from three perspectives. Likewise, there are quantum dots-based sensors which employ quantum dots as the contrast agents for improving optical responses [99]. Their short wavelength, coherence and extreme brightness should allow for the exploration of living organisms and structures much smaller than one can see with optical methods. Laser induced breakdown spectroscopy (LIBS) has proven to be a powerful technique as a rapid and accurate tool for the identification and the analysis of microorganisms and human clinical specimens. Seamless Metal Globe. The resolution of the final image is no longer limited by diffraction, but by the precision of each localization. This enhancement is localized to the tip, which has a typical diameter of 10 nm. It's basically a way of using our physics knowledge to develop tools and treatments that help humans live longer and be healthier. Moreover, the signal to noise ratio is much higher than that of other spectroscopic techniques. The advent of these smart nanomedical devices will bring about a revolution in future medicine and will radically change the way medicine has been practiced for centuries, opening new horizons especially in the fields of diagnostics and treatments, to the benefit of human health. Its members are professionals working in healthcare, education, industry and research. Finally, monitoring of the results of this therapy over time is done by sequential imaging [99]. Target heat therapy has also been developed to destroy breast cancer tumors. We did not discuss for example its impact on many medical topics, such as: Nuclear Magnetic Imaging (NMI), Positron Emission Tomography (PET), Nuclear Medicine (NM), Ultrasonography (USG), Electrocardiography (ECG), Echoencephalography, Ophthalmoscopy, Endoscopy, lasers in medicine and surgery etc. It generally concerns physics as applied to medical imaging and radiotherapy. The investigators were interested in exploring the elemental difference between gallstone compositions formed under habitat, nutrition and other environmental conditions. Figure 5: “Flying Carpet” technique usesgraphene to deliver two anticancer drugs sequentially to cancer cells. It is clear from the previous examples, that nanomaterials have proved to be highly beneficial for brightening the sensing technology and have improved the diagnostic and detection procedures. A graphene “flying carpet” was demonstrated to deliver two anti-cancer drugs sequentially to the lung tumor cells (A549) in a mouse model [164]. One example is Caelyx, a liposome carrier containing the cancer drug doxorubicin [85]. The wavelengths of the emitted spectrum were calibrated using light from a low pressure Hg- lamp, while a deuterium halogen lamp was used in calibrating the emission spectral intensities (relative sensitivity) over the entire wavelength scale. Then, the targeting nanostructures are combined with a pharmacologically active agent that can be used for therapy. This resolution is relatively low and not sufficient for the imaging and observing of biomedical structures in detail and hence many details could be lost. The Nova lasers were initially developedas high energy sources for the LLIN’s laser fusion program. The nanoparticles protect the vaccine, allowing it more time to trigger a stronger immune response. Insights Med Phys. At the Massachusetts Institute of Technology (MIT), researchers use nanoparticles to deliver vaccines [83]. A key component of biosensing is the transduction mechanism which is responsible for converting the responses of bioanalyte interactions in an identifiable and reproducible manner, using the conversion of specific biochemical reaction energy, into an electrical form through the use of the transduction mechanism. Within the scope of this review it was impossible to cover all these fields. In brief, a biosensor is defined as a sensing device (a measurement system) designed specifically for estimation of a material by using the biological interactions and then assessing these interactions into a readable form with the help of a transduction and electromechanical interpretation. The main ones are diagnostic radiology, or medical imaging, nuclear medicine and radiation oncology. (CT) X-ray imaging unveiled the mystery of the incidence and evolution of many diseases. When the Nova beam strikes the selenium foils, it vaporizes them completely to createplasma of neon- like selenium ions. The field of nanobiosensing is quite promising, especially in areas that could not be accomplished by conventional bulk materials. They have much higher intensities and power densities and moreover, they are capable of operating at specific wavelength. chemical energy Through metabolism. In fact, X-ray computed tomography had a fundamental impact on medicine. They increase the absorption of incident X-ray or gamma ray radiation, inducing electron ejection and generating free radicals. Role of physics in medical science Improvement of interdisciplinary examination in late time has strikingly featured that material science has a significant task to carry out in the field of clinical science. In contrast, the pores in normal blood vessels are just 2-6 nm in size. One of the tools to achieve this goal, is nano-imaging (known as molecular imaging) which has largelyenhanced the effectiveness of in vivo diagnostics. The more advanced (CT) camera designs have more than one head or are constructed with a ring of detectors whereas, in the case of the single and multiple head cameras, the heads are mechanically rotated around the patient to obtain the multiple projection views [21]. The use of nanotechnology in medical sciences and applications, known as nanomedicine, is a rapidly expanding field. Receptors on the cancer cell membrane bind (TRAIL) and cell surface enzymes clip the peptide and thus release the drug onto the cell surface. I suggested that the goal of medicine and supporting science is to ensure that people live long and die quickly and I contrasted this with the past scenarios. According to Feng and Liu owing to its ultra- high surface area and excellent electron mobility, graphene or graphene- based composite materials were used to modify electrodes in the electrodes in the electrochemical sensing of various biomolecules, including glucose, DNA and proteins, with high sensitivities [129,147-149]. Recent advances in medical sensing involve the development of glucose biosensors that utilize nanotubes as immobilizing surfaces for enzyme glucose oxidize; this enzyme is used for the estimation of glucose from the several body fluids. Hence, when the researchers added long DNA chains to the liquid, they were electrically pulled one by one through the graphene nanopore and the nucleotide bases, which are the letters of the genetic code, could be identified [139]. A 20% increase of the X-ray emission for nano-gold with respect to bulk gold was observed, however, the X-ray emission in the nano-copper and bulk copper was the same [166]. • Nanotechnology in medical sciences and applications. The light emitted was analyzed where it allowed the detection of trace elements in malignant tissues. This was with the invention of the scanning tunneling microscope (STM) in 1982, by Gerd Binning and Heinrich Rohrer [73]. However, recent developments focus on using nanoparticles as tracers or contrast agents. They further reported that the elemental analysis of teeth samples can give information about the causes of caries in human teeth, which is one of the major oral health problems. Taking X-ray images of slices of the body (body section radiography) is known as “tomography”. Their nano-scale allows them to preferentially penetrate and be retained by biological cells and tissues. Recently, complex drug delivery mechanisms are being developed that have the ability to get drugs through cell membranes and into cytoplasm [86].
