HIGH-THROUGHPUT FABRICATION OF MICROPARTICLES

摘要

The high-throughput fabrication of microparticles based on the double emulsion/solvent evaporation technique for screening and optimizing microparticle formulations for particular characteristics allows for the preparation of multiple microparticle formulations in parallel. The system involves the formation of an emulsion containing aqueous bubbles with the payload in an organic phase containing the polymer or polymer blend being used for the microparticles. This first emulsion is then transferred to a larger aqueous phase, and a second waterin-oil-in water emulsion is formed. The organic solvent is then removed, and the resulting particles are optionally washed and/or freeze dried. The resulting microparticles are similar or better than microparticles prepared using the traditional one formulation at a time approach. The high-throughput fabrication of microparticles is particularly useful in optimizing microparticles formulations for drug delivery.
