Abstract

Nanotechnology defined as a tiny science. By Nanotechnology we can achieve better therapeutic action, better bioavailability and better patient compliance. Pharmaceutical nanoparticles (nps) are defined as particulate dispersions or solid, submicron-sized(less than 100 nm in diameter) drug carrier that may or may not be biodegradable. Basically, nanoparticles have been prepared by using various techniques as such solvent evaporation method, spontaneous emulsification or solvent diffusion method, salting out method, nano precipitation method, polymerization method, coacervation or ionic gelation method, supercritical fluid technology. Nanoparticles have been evaluated by using parameters such as drug entrapment efficiency, particle shape, particle size, zeta potential, stability of nanoparticles in-vitro release study, applications of nanoparticles as such Tumor targeting using nanoparticulate delivery system, nanoparticles for gene delivery, tissue repair.

Keywords: Nanotechnology nano coacervation nanoparticulate tissue repair.
