Abstract: Nanotechnology plays an important role in advanced biology and medicine research particularly in the development of potential site-specific delivery systems with lower drug toxicity and greater efficiency. These include microcapsules, liposomes, polymeric microspheres, microemulsions, polymer micelles, hydrogels, solid nanoparticles etc. In the present study, preparation and characterization of biopolymeric gelatin nanoparticles for encapsulating the antimicrobial drug sulfadiazine and its in vivo drug release in phosphate buffer saline (PBS) have been investigated. The nanoparticles prepared by second desolvation process varied in a size range 200 nm and 600 nm with a drug entrapment efficiency of 50% characterized by atomic force microscopy and dynamic light scattering. The drug release from the nanoparticles occurred up to 30% in a controlled manner.
