Synthesis and functionalization of monodisperse poly (ethylene glycol) hydrogel microspheres within polyelectrolyte multilayer microcapsules

摘要

Polyelectrolyte multilayer microcapsules were used as templates to prepare monodisperse poly(ethylene glycol) (PEG) hydrogel microspheres,which can react with amine-bearing molecules.Poly(ethylene glycol) (PEG) is a widely used and accepted biomaterial.It is highly soluble in water and soluble in most organic solvents.PEG is nontoxic,and has a rapid clearance from the body.
