Medical nanotechnology uses nanotechnology principles to address health issues. It offers targeted surgical instruments, drug delivery systems, implants, biosensors, and prosthetics. However, concerns exist about nanoparticles interfering with bodily functions. The focus is on ensuring safety for patients and healthcare professionals.
Medical nanotechnology is a branch of nanotechnology that applies the principles in this field to health issues. Nanotechnology is a broad spectrum of scientific activities involving manufacturing and processing that occurs on a molecular scale. There are numerous potential applications for medical nanotechnology, and in its early stages, many people were quite excited about the huge changes that could occur in the medical world with the assistance of medical technology.
Because nanotechnology operates on such a small scale, it presents the opportunity to create precisely targeted surgical instruments, drug delivery systems, and implants. Nanobots, for example, could be used to perform a non-invasive medical imaging study inside the body or to perform surgical procedures. Nanomaterials can also be implanted in the body; for example, someone with a badly damaged bone or joint could be treated with nanoparticles that would encourage new growth, causing the damaged tissue to regrow.
Medical nanotechnology also makes cellular repair possible at the molecular level and offers a variety of opportunities for drug delivery. Drugs developed through nanotechnology could penetrate cells directly, for example, or nanoparticles could be engineered to target cancer cells, deliver drugs, or provide a focal point for radiation. Medical nanotechnology can also be used to make biosensors that can be implanted in patients for monitoring, along with medical devices designed to be permanently implanted such as pacemakers.
This field also has a number of implications for prosthetics. Nanomaterials could be used to give people more control over prosthetic limbs and potentially do things like restore eye function. Several militaries have invested in medical nanotechnology in order to develop new treatments for wounded soldiers. The field also creates potential for the development of devices that could improve human function, much to the delight of science fiction authors around the world.
Some concerns have been raised about the use of nanomaterials in the medical field. Some people are concerned that nanoparticles could interfere with normal bodily function, making people ill, or that non-devices could spiral out of control, resulting in activities beyond what they were designed for. Therefore, much of medical nanotechnology focuses on making it safe for patients and healthcare professionals. The history of medicine is filled with examples of concepts and procedures that were initially viewed with deep skepticism and subsequently widely embraced; most people today, for example, largely agree to washing their hands regularly, but this idea was heretical when it was introduced in the 1800s.
