Drug-Loaded Polymer Microparticles with Arbitrary Geometries

3 Drug-Loaded Polymer Microparticles with Arbitrary Geometries 

The carrier geometry is a key parameter of drug delivery systems and has a significant impact on the drug release rate and interaction with cells and tissues. 

A piezoelectric inlqet printing system has been used as a simple and convenient approach for fabrication of drug-loaded pol5mier microparticles with well-defined and controlled shapes (87).
