| Abstract: | Objective：To develop an emulsion solvent evaporation technique for the preparation of nanoparticles.Methods：The effects of different formulation and technics factors on the particle size,drug loading,and drug encapsulation efficiency were evaluated by single factor design and orthogonal design.Results：The nanoparticles prepared by emulsion solvent evaporation technique were round and uniform in size.The drug encapsulation efficiency of most preparations were more than 50%,and their particle size could be controlled.Conclusions：An emulsion solvent evaporation technique was optimized to manufacture nanoparticles meeting different requirement. |
