Challenges and Benefits of Nanotechnology in Medicine
While we may never have imagined it, nanotechnology is revolutionizing the way we do just about everything. This is because of its nanoscopic size, and its ability to be used in applications ranging from cosmetics to electronics. Researchers are currently exploring nanotechnology’s potential for medical applications, such as cancer therapies. But we must take care to make sure these technologies do not pose a danger to our health, or to the environment. This article will discuss some of the challenges and benefits of nanotechnology.
As we make materials ultra-small, their physical and chemical properties change. The color of gold changes depending on the size of the chunks, so when it reaches a thickness of ten to one hundred nanometres, it appears reddish, purple, or green. In the nanoscale, gold acts as a catalyst, whereas at the macro/micro scale, it is chemically inert. For example, the process of etching a material can result in the production of nano-scale materials.
Using nanotechnologies in medicine is called nanomedicine. The application of nanotechnologies in medicine is the goal of this discipline. This new technology has tremendous potential to revolutionize several fields of medicine, including drug delivery, gene therapy, and diagnostics. Researchers have developed several nanoparticles and nanomaterials that may be used in clinical settings. Below, we discuss some of the most common types of nanoparticles and nanomaterials. These technologies have tremendous potential for medical applications and have already made a significant impact on our lives.
However, there is a significant gap in our knowledge of the toxicity of nanomaterials. Since nanoparticles can be translocated inside the body, they may interact with biological systems. It is therefore essential to understand the intrinsic toxicity of the material, the level of exposure, and how these effects are influenced by its presence in the environment. More research is needed in order to better understand the potential toxicity of engineered nanomaterials in humans.
Nanoparticles can be used in the treatment of cancer. Researchers have created nanofibers that attack metastatic tumors, which grow from cancer cells that have spread to other parts of the body. MIT is also working on nanoparticles that synthesize potential cancer drugs. Another example of nanotechnology in medicine is the development of nanofibers for wound dressings and surgical textiles. These fibers can also be used in tissue engineering and artificial organ components.
Another promising application for nanotechnology in biomedicine is in drug delivery. Nanoparticles of protein can be programmed to deliver specific signals to cells. Unlike conventional methods, they do not break down in the body before reaching their destination. These nanoparticles can also be more targeted than their conventional counterparts. Thus, they can be used as diagnostic tools to help identify diseases and treat them. If they prove to be successful in clinical studies, they can revolutionize the field of medicine.
