General Description
8-Arm PLGA-NHS 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 NHS ester groups.
The NHS ester functionalities rapidly react with amine-containing molecules to form stable amide bonds, 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.
