Abstract

A dynamic hydrogel that sequentially responds to two independent but interrelated physical and biomolecular signals was reported in this work. Once hit by an external light signal, an immobilized internal molecular signal is activated and freed via photoreaction; and subsequently the freed molecular signal works as a self-programming factor of the hydrogel to induce the dissociation of a biomolecular complex to release protein via a hybridization reaction. Notably, pulsatile external light input can be converted to periodical protein output from the hydrogel to regulate cell migration. Thus, this hydrogel holds potential as a self-programming platform for biological and biomedical applications such as controlled release of bioactive substances.
