The molecular chain of COOH-PEG-PCL consists of hydrophilic PEG blocks and hydrophobic PCL blocks, a functional amphiphilic block copolymer. The carboxylic acid functional group at the end of the chain can be quickly and easily surface functionalized for the preparation of nanoparticles and micelles for targeted drug delivery. COOH-PEG-PCL is one of the biodegradable ABC polymers most commonly used for drug delivery. It is possible to prepare well-defined nanoparticles with adjustable size and properties by changing the molecular weight ratio between hydrophilic and hydrophobic blocks and by controlling formulation parameters.
