Application

PEG-SS-PCL is a redox responsive, biocompatible, amphiphilic block copolymer composed of a hydrophilic poly(ethylene glycol) (PEG) block and a hydrophobic poly(ε-caprolactone) (PCL) block, with a reducible disulfide linkage between blocks. This polymer can be fabricated into Glutathione (GSH) responsive nanoparticles which can be used as an intracellular drug delivery system.
