General Description
8-Arm PLGA-NH₂ is a highly branched biodegradable polyester designed for advanced drug delivery and biomedical applications. The polymer consists of eight PLGA chains attached to a central multifunctional core, creating a star-shaped architecture with multiple terminal primary amine groups.
The amine functionalities readily react with NHS esters, activated carboxylic acids, aldehydes, isocyanates, and other amine-reactive compounds, enabling efficient conjugation of peptides, proteins, antibodies, fluorophores, nucleic acids, targeting ligands, and other biomolecules. Compared with conventional linear PLGA derivatives, the eight-arm architecture offers substantially higher reactive group density and increased versatility for the preparation of multifunctional nanoparticles, targeted delivery systems, and crosslinked biomaterials.
Upon hydrolysis, the polymer degrades into lactic acid and glycolic acid, making it suitable for biodegradable pharmaceutical formulations, regenerative medicine, and biomaterials development.
