Abstract

The term nanotechnology encompasses the production of new materials at nano scale. Nano particles with interesting shapes can be prepared by different methods like physical and chemical method. Now day‟s biological methods of synthesis are used because it is environment friendly, cost effective, and easily scaled up process for large scale synthesis. Nano particles have vast applications in magnetic devices, microelectronics, bio medicals, electro catalysis, photo catalysis, anticorrosive coatings and powder metallurgy, out of which clinical applications are in high demand due to their biocompatibility, antibacterial activity, anti-inflammatory activity, effective drug delivery ,tumour targeting , bioactivity, bioavailability and bio absorption. The goal of the present study is to develop better understanding about the different aspects of Nano particle synthesis and biomedical applications.

Keywords: Nanotechnology, Nano-particles, Nanoparticle synthesis, biocompatibility, antibacterial activity, anti-inflammatory activity.
