Abstract:
A method of preparing a polyacrylamide hydrogel comprising:(a) providing a liquid solution comprising a polyacrylamide reactive prepolymer, wherein the polyacrylamide reactive prepolymer comprises a copolymer of acrylamide and one or more compounds selected from the group consisting of N-(6-acryloylhexyl)-2,3-dimethylmaleimide, vinyl cinnamate, and acrylic acid, wherein the acrylic acid is functionalized with a compound selected from the group consisting of glycidyl methacrylate, hydroxy ethyl acrylate, and hydroxy propyl acrylate; (b) placing a liquid solution of said polyacrylamide reactive prepolymer on a solid support; and (c) photochemically crosslinking said polyacrylamide reactive prepolymer to obtain said polyacrylamide hydrogel.
