Abstract
A polymeric hydrogel microparticle that contains polyacrylamide and chitosan, the chitosan uniformly incorporated in a polyacrylamide matrix. The microparticle, having a coefficient variation of 0 to 2% and containing macropores with an average size of 1 to 60 nm, is capable of transporting biomolecules conjugated to it. Also disclosed are a method of fabricating such a microparticle in a micromold via photo-induced radical polymerization and a one-pot method of conjugating biomolecules to polymeric hydrogel microparticles.
