Nanomedicine is a branch of medicine that uses the Nanotechnology for the prevention and treatment of disease in the human body. This evolving discipline has the potential to dramatically change medical science. Nanomedicine fuses the usage of nanoscale materials, for instance, biocompatible nanoparticles and nanorobots, for examination, conveyance, distinguishing or incitation purposes in a living structure. Current issues for nanomedicine incorporate understanding the issues related to lethality and environmental impact of nanoscale materials , Preparation of nano-prescriptions and its application. Research are being completed give a wide audit of magnetic nanoparticle, Silver nanoparticles, Gold nanoparticles explore with a special focus on the synthesis, functionalization and medicinal uses of these particles.
