Novel ways of targeted drug delivery using nano capsules and functionalized nanoparticles have been a primary focus of nanomedicine research to date. Existing drugs can be Nano formulated to make them easier to administer, safer, and more effective. Nano-enhanced diagnostic systems have also sparked a lot of scientific attention. In today's medical world, personalized medicine is a huge shift. It tries to move away from the existing approach of prescribing standard doses of typical medications to every patient for a disease, instead focusing on finding the exact drug and dose required based on the patient's physiology. Nanotechnology can aid with these advancements in a variety of ways, including making diagnostic techniques simpler, faster, or less intrusive by using less tissue.
