NATURE OF NANOPARTICLES AND THEIR APPLICATIONS IN TARGETED DRUG DELIVERY

Abstract

Nanotechnology is a rapidly growing field and has secured a prominent rank in medicinal field. They find applications in cancer therapy, cell bio-imaging, in treatment of neurodegenerative diseases, in targeted drug delivery at cell or tissue level and also in the regeneration of tissues and different organs. NPs like liposomes and dendrimers are widely used as nanocarriers. They can be successfully employed in drug delivery due to their specific properties like bioavailability, their biocompatibility and accumulation only at the specific target site without harming or affecting other non target tissues. They are superior in targeted drug delivery as compared to the conventional methods of drug delivery. Nanoparticles (NPs) are synthesized by various techniques and approaches.
