General Description
Acryloyl-PLLA-PEG-Alkyne (ACRL-PLLA-PEG-ALK) is a biodegradable amphiphilic block copolymer designed for advanced bioconjugation and drug delivery applications. The hydrophobic poly(L-lactide) (PLLA) segment promotes self-assembly into polymeric micelles and nanoparticles while providing controlled biodegradation and excellent mechanical properties. The hydrophilic polyethylene glycol (PEG) segment enhances aqueous solubility, colloidal stability, prolonged circulation, and biocompatibility.
The terminal acryloyl (ACRL) group undergoes efficient free-radical polymerization and thiol-Michael addition reactions, allowing incorporation into hydrogel networks and polymer matrices. The opposite alkyne (ALK) group provides a versatile handle for copper-catalyzed azide-alkyne cycloaddition (CuAAC) or copper-free click chemistry with azide-functionalized biomolecules, peptides, antibodies, polymers, and nanoparticles.
This dual-functional PLLA-PEG copolymer is an excellent platform for preparing multifunctional nanoparticles, injectable hydrogels, targeted drug delivery systems, tissue engineering scaffolds, and surface-engineered biomaterials.
