PEG Copolymers

Polyethylene glycol (PEG) has ubiquitous use in biomaterials, due to its good biocompatibility, non-toxicity and low immunogenicity. With the rapid development of diblock copolymers in biomedicine, nanomaterials, sustained release and photonic crystals fields, there are more and more studies on the use of PEG as basic skeleton to develop copolymers. PEGylated copolymers mainly include carbohydrates, hyaluronic acid, polyamino acid and others. PEGylated copolymers have been developed for a wide range of applications. In the biomedical field, the applications mainly focus on drug delivery, drug release, drug solubility enhancement, microencapsulation, implants, tissue scaffolding and others. Biodegradable polyesters, including those made of caprolactones, have been approved for clinical use.
