General Description
4-Arm PLGA-N₃ is a multifunctional biodegradable polyester designed for advanced drug delivery and biomedical applications. The polymer consists of four PLGA chains radiating from a central core, with each arm terminating in a reactive azide group.
The azide functionalities readily participate in copper-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC) reactions, enabling efficient conjugation of peptides, proteins, antibodies, fluorophores, targeting ligands, and other biomolecules. Compared with linear PLGA derivatives, the multi-arm architecture provides significantly higher functional group density, allowing efficient preparation of multifunctional nanoparticles and targeted delivery systems.
Upon hydrolysis, the polymer degrades into lactic acid and glycolic acid, making it suitable for biodegradable pharmaceutical and biomedical applications.
