Nanotechnology comprises of creation of nanoscale particles by up scaling or downscaling minor or major materials, respectively. Nanoparticle, by convention, size in the range of 1 to 100 nm in size. It explores the electrical, optical, and magnetic potential, along with structural properties at molecular and atomic level. It has the capacity to revolutionize medical and biotechnology tools and methods for portable, economical, and easy to use applications. This study aims to present an overview of nanoparticles, with special reference to their mechanism of biosynthesis and their types. Nanoparticles can be synthesized chemically or biologically with different protocols either aggregating ionic particles or breaking down larger pieces into smaller ones. Metallic nanoparticles that have significant role in industries and are of different types, namely, Gold, Silver, Iron, Alloy, magnetic etc.
