Claim:
1. A photopolymerization system for producing a thiol-ene hydrogel comprising at least one thiol compound and at least one olefin compound, wherein: (a) the at least one thiol compound comprises m number of reactive thiol groups; (b) the at least one olefin compound comprises n number of reactive ene groups; (c) each of n and m is an integer of at least 2, provided the sum of n+m is at least 5; and (d) the at least one thiol compound and the at least one olefin compound are capable of undergoing photopolymerization in the presence of water to form a biocompatible thiol-ene containing hydrogel; and wherein the at least one thiol compound comprises a polymeric moiety selected from hyaluronic acid and gelatin.
