Abstract

Core-shell PLLA microparticles were successfully fabricated using a novelcoaxial nozzle design. These particles were synthesized with differentcomponents in the core/shell layers representing three classes of systems ofinterest for drug delivery applications: PVA/PLLA, PLLA/PEG, and oleicacid/PLLA. The components were characterized for their physical propertiesand interfacial energies, and optimal conditions for the operation weredetermined. To facilitate the particle characterization, each phase wasdoped with a different fluorescent dye to aid in the confirmation of acore/shell structure via fluorescence microscopy.
