The production of microspheres involves several techniques, each with its own advantages and disadvantages:
- Spray Drying: This method involves spraying a solution containing the desired materials into a chamber with hot gas, evaporating the solvent and leaving behind solid microspheres. - Emulsion Polymerization: In this process, monomers are polymerized within droplets of an emulsion, forming solid microspheres. - Solvent Evaporation: This technique involves dissolving the material in a volatile solvent, forming an emulsion, and then evaporating the solvent to form solid microspheres.
