PLGA(3k)-PEG(2k)-N3 is an azide functionalized block copolymer. The terminal azide is reactive with alkyne via SPAAC/CuAAC. In water, the polymer can form micelles where the core contains poly(lactide-co-glycolide) (PLGA) and the shell are made of hydrophilic PEG. It can be used to prepare drug loaded nanoparticles in drug delivery system. Reagent grade, for research purpose.
