A review on nanoparticles – preparation and evaluation parameters

RENU TIRUWA

Abstract


Nanotechnology defined as a tiny science. Design characterization, production and applications of structures, devices and systems by controlling shape and size at nanometer scale is refers to nanotechnology. Nanotechnology by which we can achieve better therapeutic action, better bioavailability and better patient compliance. Several nanoformulations are successfully used for brain delivery which includes nanoparticles system (polymeric/solid lipid), liposomes, dendrimer‟s, nanoemulsions, nanosuspension and ligand mediated nanosystems.Nanoparticles are defined as particulate dispersions or solid particles drug carrier that may or may not be biodegradable. Several techniques are used for preparation of nanoparticles like Solvent Evaporation, Double Emulsification method, Emulsions - Diffusion Method, Nanoprecipitation, Coacervation method, Salting Out Method, Dialysis and Supercritical fluid technology. Nanoparticles are subjected to several evaluation parameters such as yield of nanoparticles, Drug Content / Surface entrapment / Drug entrapment, Particle Size and Zeta Potential , Surface Morphology, Polydispersity index, In-vitro release Study, Kinetic Study, Stability of nanoparticles.

Keywords


Advantage of nanoparticles,evaluation of nanoparticles,nanoparticles a novel drug delivery system,preparation technique.
