Nanoparticles are solid colloidal elements varying in the size from 10 to 1,000 nm. It is generally made up of macromolecular material which can be natural or synthetic in nature. On the other hand, nanotechnology is the technology for fabrication, design as well as manipulation of nanometer scale systems in the range of 1-100 nm. Nanoparticle technology or nanotechnology is an evolving and rapidly growing technology in all across the globe. It has been noticed that presently there are around 1,300 nanoparticle technology based products available in the market. The nanoparticle technology handles the planning, processing, usage and characterization of nanoparticles.
