APP68: Plastic Injection Molded Microneedles

Abstract: 

The objective of this research is to design, fabricate, characterize, and demonstrate injection-molded, plastic microneedles. Deep Reactive Ion Etching (DRIE) will be used to fabricate silicon die inserts and an “investment casting” technique used to define the inner bore (lumen) of the needle. These silicon die inserts will be incorporated into a standard plastic injection molding machine to transfer the micron-scale features from the silicon die to the plastic microneedles. It is expected to fabricate microneedles from polycarbonate, a premium plastic.
