ABSTRACT:
A method of forming microspheres of a bioactive material, such as a protein polymer or drug by nebulizing a solubilized form of a material to be encapsulated and an encapsulating material, such as albumin, in a stirred chilled solvent system comprising a vegetable oil, mineral oil and/or a lower alcohol such that the formed microspheres demonstrate intracellular bioactivity when taken up by macrophages.
