摘要：
A macroporous polymeric hydrogel microsphere that contains poly(ethylene glycol), chitosan, and water. The hydrogel microsphere, having a diameter of 50-250 gm and a mesh size of 5-100 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.
