Application

Poly(ethylene glycol) has been used as a non-absorbing polymer in aqueous dispersion or active gel assembly to stimulate the formation of filament bundles through depletion interaction.

Biochem/physiol Actions

Polyethylene glycol (PEG) is a synthetic polymer that is used as a gold standard in bioconjugation and nanomedicine to extend blood circulation time and enhance drug efficacy. PEG-conjugated drugs are considered safe for use in humans and are approved by the U.S. Food and Drug Administration (FDA). PEG has several biomedical applications, including biosensing, imaging, and tissue engineering. It also repels protein adsorption and lowers the liver uptake, which helps in coating nanoparticles.

General description

Polyethylene glycol (PEG) is a polyether compound that is used as an additive in cosmetics, pharmaceuticals, and food. It consists of repeated ethylene glycol units[-(CH2CH2O)n].
