Emulsion click microspheres: morphology/shape control by surface cross-linking and a porogen

Abstract

Click chemistry plays a dual role in emulsion microsphere (MS) preparation as both an in situ cross-linking method and a bioconjugation route. The morphology/shape of the MSs can be adjusted by applying surface click cross-linking and a porogen simultaneously. The emulsion click cross-linked MSs have potential application in drug delivery, and the preserved azide groups could be used for further surface conjugation with bioactive molecules.
