General description

Poly(ethylene glycol) (PEG) is a biocompatible water soluble poly(ether) with low toxicity. It is majorly used as a biopolymer for the surface modification of biomaterials. Its properties include hydrophilicity and non-immunogenicity.

Application

PEG can be used in the formation of polymeric hydrogels for the formation of biomedical applications.
