Description
General Description
PCL-PEG-Maleimide is a functional biodegradable copolymer designed for nanoparticle engineering and thiol-specific bioconjugation applications. The hydrophobic PCL segment forms the core of nanoparticles and micelles capable of encapsulating hydrophobic drugs, proteins, peptides, and imaging agents, while the PEG segment forms a hydrophilic corona that enhances colloidal stability and reduces nonspecific protein adsorption.
The terminal maleimide group selectively reacts with sulfhydryl-containing peptides, proteins, antibodies, enzymes, and targeting ligands under mild conditions to form stable thioether linkages. PCL-PEG-Maleimide combines the sustained-release properties of PCL with the versatility of maleimide chemistry, making it useful for targeted drug delivery systems, polymer therapeutics, imaging agents, and advanced biomaterials.
