Controlled Protein Delivery Based on Enzyme‐Responsive Nanocapsules

Abstract
Enzyme‐responsive protein nanocapsules are synthesized to release their protein cargoes in response to specific enzymes secreted in certain cellular events with both specificity and with a controlled rate by composition tuning. The unique nanocapsule structures protect the encapsulated proteins during hydrogel synthesis, providing a new direction for responsive protein delivery according to specific cellular events or the local environment.
