Description
PLLA(5k)-PEG(5k)-N3 is a triblock copolymer consisting of poly-L-lactic acid (PLLA) with a molecular weight of 5 kDa, a polyethylene glycol (PEG) segment of the same molecular weight, and a terminal N3 functional group. The PLLA-PEG structure provides hydrophilicity and biocompatibility, while the N3 group can be used for further conjugation or targeting applications.
