Nanotechnology and Health

Nanomedicine is a reality nowadays. The first generation nanomedical capabilities, in the form of functionalized nanoparticles, comprising a wide range of organic and inorganic materials at various nanoscale dimensions, initially emerged in the early 1990s, and have since undergone dramatically rapid expansion. Nanomedicine is one of the important applications of nanotechnology. The development of smaller, less invasive, smarter, more precise, and more efficient medical devices is a fast-expanding global trend. The creation of specialized nanoparticles for use in medicine, such as magnetic nanoparticles and gold nanoshells, is advancing daily. This development is happening while nanomedicine is still in its early stages. As reported, superparamagnetic iron oxide nanoparticles are being used to specifically target and thermally destroy cancer cells without causing collateral damage to surrounding healthy cells and tissues.
