Claim 6:
7. A method of making a hydrogel system as defined in claim 5, comprising:
i) combining an aqueous solution of a first side-chain functionalized backbone polymer functionalized with an activated alkene or epoxy group with a polymer matrix selected from alginate, agarose, cellulose sulphate and combinations thereof; and
ii) adding an aqueous solution of a polyethylene glycol (PEG)-dithiol having a molecular weight in the range of from about 200 to 1,000,000 Daltons under conditions that permit crosslinking, or combining the first side-chain functionalized backbone polymer with a second side-chain functionalized backbone polymer functionalized with a protected thiol group in a polymer matrix selected from alginate, agarose, cellulose sulphate and combinations thereof, and adding a deprotecting agent to the solution which exposes the thiol group of the second side-chain functionalized backbone polymer.
