By Catharine Paddock PhD Nanotechnology, the manipulation of matter at the atomic and molecular scale to create materials with remarkably varied and new properties, is a rapidly expanding area of research with huge potential in many sectors, ranging from healthcare to construction and electronics. In medicine, it promises to revolutionize drug delivery, gene therapy, diagnostics, and many areas of research, development and clinical application. This article does not attempt to cover the whole field, but offers, by means of some examples, a few insights into how nanotechnology has the potential to change medicine, both in the research lab and clinically, while touching on some of the challenges and concerns that it raises.
Nanotechnology Images Nanotechnology in Medicine Nanomedicine For centuries, man has searched for miracle cures to end suffering caused by disease and injury. According to Robert A. Freitasnanomedicine is "1 the comprehensive monitoring, control, construction, repair, defense, and improvement of all human biological systems, working from the molecular level, using engineered nanodevices and nanostructures; 2 the science and technology of diagnosing, treating, and preventing disease and traumatic injury, of relieving pain, and of preserving and improving human health, using molecular tools and molecular knowledge of the human body; 3 the employment of molecular machine systems to address medical problems, using molecular knowledge to maintain and improve human health at the molecular scale.
For instance, Nanotechnology in medicine is a fine line between medical and non-medical uses of nanotechnology for Nanotechnology in medicine, therapeutic and preventive purposes e.
The question of whether nanotechnology should be used to make intentional changes in or to the body when the change is not medically necessary is just one hot topic in a long list of concerns. According to an expert group of the European Medicines Evaluation Agency Source " Reflection paper on nanotechnology-based medicinal products for human use ""the majority of current commercial applications of nanotechnology to medicine is geared towards drug delivery to enable new modes of action, as well as better targeting and bioavailability of existing medicinal substances.
Novel applications of nanotechnology include nanostructure scaffolds for tissue replacement, nanostructures that allow transport across biological barriers, remote control of nanoprobes, integrated implantable sensory nanoelectronic systems and multifunctional chemical structures for drug delivery and targeting of disease.
A recent ObservatoryNano report lists nanotechnological applications in health and medicine pdf. The two main areas in nanomedicine are: Nanomedicine Diagnostics In the past few decades, imaging has become a critical tool in the diagnosis of disease.
As with any advance in diagnostics, the ultimate goal is to enable physicians to identify a disease as early as possible. Nanotechnology is expected to make diagnosis possible at the cellular and even the sub-cellular level. Quantum dots in particular have finally taken the step from pure demonstration experiments to real applications in imaging.
In recent years, scientists have discovered that these nanocrystals can enable researchers to study cell processes at the level of a single molecule. This may significantly improve the diagnosis and treatment of cancers. Fluorescent semiconductor quantum dots are proving to be extremely beneficial for medical applications, such as high-resolution cellular imaging.
While quantum dots could revolutionize medicine, unfortunately, most are toxic.
Nanotechnology looks likely to revolutionize medicine in the future. To go where ‘no man has gone before’ is no longer exclusively on an interstellar scale, but now on an microscopic scale as ashio-midori.comrticles are so small that thousands of them could fit onto the head of a pin. The medical advances that may be possible through nanotechnology range from diagnostic to therapeutic, and everything in between (also check out our primer How does nanotechnology work). A recent ObservatoryNano report lists nanotechnological applications in health and medicine (pdf). Oct 19, · There is increasing optimism that nanotechnology applied to medicine and dentistry will bring significant advances in the diagnosis, treatment, and prevention of disease. Growing interest in the future medical applications of nanotechnology is leading to the .
However, recent studies conducted at the University of California, Berkeley, have shown that protective coatings for quantum dots may eliminate toxicity. Nanomedicine Therapy In terms of therapy, the most significant impact of nanomedicine is expected to be realized in drug delivery and regenerative medicine.
Nanoparticles enable physicians to target drugs at the source of the disease, which increases efficiency and minimizes side effects. They also offer new possibilities for the controlled release of therapeutic substances.
A major focus of this research is artificial activation and control of adult stem cells. Peptide amphiphiles that support cell growth to treat spinal cord injury; magnetic nanoparticles and enzyme-sensitive nanoparticle coatings that target brain tumors; smart nanoparticle probes for intracellular drug delivery and gene expression imaging, and quantum dots that detect and quantify human breast cancer biomarkers are just a few of the advances researchers have already made.
Interestingly enough, there could be massive shifts in economic value among pharmaceutical companies. While the new nanomedicines open up enormous market and profit potentials, entire classes of existing pharmaceuticals such as chemotherapy agents worth billions of dollars in annual revenue would be displaced.
Other areas that are increasingly attracting interest from nanotechnology researchers are tissue engineering, nanosurgery, and nanoparticle-enabled diagnostics and drug delivery read more: Also take an up-to-date look at how nanoelectronics will change medicine.
Nanotechnology to cure diseases has many potential impacts on cancer research, especially cancer drugs. In particular, this technology can help facilitate research and improve molecular imaging, early detection, prevention, and treatment of cancer.
