Abstract:
The present disclosure provides light-sensitive protein hydrogels, and methods of their use thereof. The hydrogels can be used for cell encapsulation, culturing, and selective release under appropriate light conditions.

Claim (Index 17):
A method for producing a light-responsive hydrogel biopolymer matrix, the method comprising dissolving one or a plurality of light-responsive gelation initiator complexes comprising the protein photoreceptor CarH C  and the multi-dentate ligand adenosylcobalamin connected to one or a plurality of a first extracellular matrix protein fragments and two or more cross-linkable proteins connected to one or a plurality of a second extracellular matrix protein fragments in an aqueous solution to form a gelation mixture under light which does not comprise a wavelength of less than about 600 nm,\n wherein the first extracellular matrix protein fragments and second extracellular matrix protein fragments are independently selected from elastin fragments which comprise a repeating polypeptide having the sequence of (VPGXG) n  (SEQ ID NO: 23), wherein X represents valine or glutamate, the ratio of valine to glutamate ranges from 10:1 to 1:10, n is an integer selected from 2 to 25, and the two or more cross-linkable proteins are SpyTag and SpyCatcher.
