Nanoparticle: An overview of preparation and

2014-7-8  Emulsion-Solvent Evaporation Method: This is one of the most frequently used methods for the preparation of nanoparticles. Emulsification-solvent evaporation involves two steps. The first step requires emulsification of the polymer solution into an aqueous phase. During the second step polymer solvent is evaporated, inducing polymer precipitation as nanospheres. The nano particles are collected by ultracentrifugation and washed with distilled water to remove stabilizer residue or any free drug and lyophilized for storage (Song et al., 1997). Modification of this method is known as high-pressure emulsification and solvent evaporation method (Jaiswal et al., 2004). This method involves preparation of a emulsion which is then subjected to homogenization under high pressure followed by overall stirring to remove organic solvent (Soppinath et al., 2001).The size can be controlled by adjusting the stirring rate, type and amount of dispersing agent, viscosity of organic and aqueous phases and temperature (Tice et al., 1985).However this method
