During the last decade the nanotechnologists began research on applications of nanomaterials for medicine
and therapeutics. Various nanoparticles (nanomedicines) are being used worldwide for the diagnosis and management
in a number of disorders including cancer and neurodegenerative disorders. The successful non-viral gene
therapy is now possible with the advancements in nanotechnology. Mostly nanoparticles are divided into two main
classes: organic and inorganic nanoparticles. Diverse features of nanomedicines with surface modification help to make them biocompatible
with addition of varying polymer that facilitates targeted delivery of drug and its controlled release into the cells, tissues and organs.
Liposomes, quantum dots, silver and gold nanoparticles are the most common examples of nanomedicines.
Keywords: Cancer, gene therapy¸ liposomes, nanomedicines, neurodegenerative disorders, quantum dots, silver and gold nanoparticles.
