Abstract

A conceptually new approach to polymer-based enzyme-triggered release is described, whereby the selective catalytic action of (disease-specific) enzymes triggers a charge-induced swelling response in chemically crosslinked hydrogel particles, resulting in the release of physically entrapped macromolecules (see figure).
