PEG-PCL microspheres
Introduction: PEG-PCL microspheres are a widely used amphiphilic polymer microsphere that combines the properties of polyethylene glycol (PEG) and polycaprolactone (PCL), offering excellent biocompatibility, biodegradability, and biosafety. These microspheres exhibit superior performance in drug delivery, tissue engineering, and regenerative medicine. Their unique physicochemical properties endow them with broad application potential in multiple fields
