Description
General Description
PBCL-PEG is a biodegradable amphiphilic block copolymer consisting of hydrophobic poly(α-benzyl carboxylate-ε-caprolactone) (PBCL) and hydrophilic polyethylene glycol (PEG). The PBCL segment contains pendant benzyl ester functionalities that provide opportunities for further chemical modification and can influence drug-loading behavior and nanoparticle properties.
PBCL-PEG readily self-assembles into polymeric micelles and nanoparticles in aqueous media, making it a valuable material for drug delivery, nanomedicine, and biomaterials research.
