Metal ion and light sequentially induced sol-gel-sol transition of a responsive peptide-hydrogel

We developed a new responsive peptide hydrogel FmocFFpS C (oNB)-PEG, which could achieve gel formation induced by calcium ions and sequential dissolution stimulated by light. It provides a potential delivery system for the efficient encapsulation of drugs and their controlled release in a spatial and temporal way. We developed a new responsive peptide hydrogel that could achieve a sol-gel-sol transition sequentially induced by calcium ions and light.
