Description
General Description
PLGA-PEG-N₃ is a functional biodegradable block copolymer that combines the controlled degradation properties of poly(lactic-co-glycolic acid) (PLGA) with the hydrophilicity and stealth characteristics of polyethylene glycol (PEG). The amphiphilic structure readily self-assembles into polymeric micelles and nanoparticles in aqueous environments, making it a widely used material for drug delivery applications.
The terminal azide group enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC) reactions for conjugation with peptides, proteins, antibodies, fluorophores, nucleic acids, targeting ligands, and other biomolecules. PLGA-PEG-N₃ is commonly used in targeted nanomedicine, polymer therapeutics, imaging probes, and advanced biomaterials research.
