Acid-degradable solid-walled microcapsules for pH-responsive burst-release drug delivery

Chem Commun (Camb). 2011 Jan 14;47(2):665-7. doi: 10.1039/c0cc04190d. Epub 2010 Nov 26.

Abstract

Acid-degradable microcapsules were prepared via an interfacial polymerization. Degradation of the thin wall of the capsules leads to all-or-nothing cargo release. The only byproducts of degradation are acetone, and a non-toxic triamide. Proof-of-concept experiments showed that cargo can be delivered to and released in cells.
