  • Method of Encapsulating a Material Using Solvent Removal Technique, and Microspheres/Nanospheres/Matrix Made Therefrom Having Sustained Release Properties
    Publication number: 20130095188
    Abstract: A method of encapsulating a material includes providing a polymer solution including a solvent, and an aqueous solution including a hydrophilic material, mixing the polymer and aqueous solutions, sonicating the mixed solution to obtain a water-in-oil (W/O) emulsion, mixing the water-in-oil emulsion with an oil solution, sonicating the mixed solution to obtain a water-in-oil-in-oil (W/O/O) emulsion, and stirring the water-in-oil-in-oil emulsion in a bath to form a precipitate of encapsulated material and separate the solvent.
