Fabrication of Particulate Reservoir‐Containing, Capsulelike, and Self‐Folding Polymer Microstructures for Drug Delivery

Particulate polymer microdevices are fabricated using protocols based on a transfer-molding process that allows the controlled assembly of multiple materials to produce functional devices. Specifically, protocols for reservoir-containing (see image; scale bar=100 μm), capsulelike, and self-folding polymer microdevices are presented. The encapsulated materials are not exposed to high temperatures or caustic solutions, which is important in drug-delivery applications.
