Abstract
Disclosed is a macroporous polymeric hydrogel microsphere that contains polyacrylamide and chitosan. The hydrogel microsphere, having a diameter of 50-250 μm and an average pore size of 1-60 nm, is capable of transporting biomolecules conjugated to it. Also disclosed is a method of fabricating the microsphere based on a micromolding technique utilizing surface tension-induced droplet formation followed by photo-induced polymerization.
