Description
General Description
PLLA-MPEG is a biodegradable diblock copolymer consisting of a hydrophobic poly(L-lactide) segment covalently linked to a hydrophilic methoxy polyethylene glycol chain. The PLLA block provides biodegradability and mechanical strength, while the MPEG block imparts water solubility, steric stabilization, and biocompatibility.
Due to its amphiphilic nature, PLLA-MPEG readily self-assembles into polymeric micelles and nanoparticles in aqueous environments. These nanostructures are capable of encapsulating hydrophobic drugs and imaging agents, making PLLA-MPEG a valuable material for controlled drug delivery and nanomedicine applications. The polymer is also extensively used in tissue engineering scaffolds, biodegradable implants, and biomaterials research.
