This review is about nanocrystal technology and applications of nanocrystals based on drug delivery. Nanocrystal technology is applied to the drug molecules to access for good drug delivery as nano dimensioned carrier. Nanoparticle has at least one dimension smaller than 100 nanometers. The major properties of nanoparticles are increases dissolution velocity by surface area enlargement and increase in saturation solubility. Nanoparticle’s productions are done with different methods such as precipitation method, Milling method, and homogenized method. Nanoparticles has got wide range of applications based on drug delivery such as gastrointestinal tract, brain, tumor cell targeting, respiratory tract, and gene delivery. Keywords: Drug delivery, Nanoparticles, nanosized, surface area, etc
