Polyethylene glycol (PEG), also identified as polyethylene oxide (PEO) or poly(oxyethylene) (POE), stands as a synthetic polyether recognized for its hydrophilic nature and biocompatibility. Generally, substances possessing a molecular weight below 20,000 g/mol are denoted as PEGs, while those exceeding 20,000 g/mol are labeled as PEOs. These polymers exhibit solubility in water as well as numerous organic solvents, including ethanol, acetonitrile, toluene, acetone, dichloromethane, hexane, and chloroform. 

APPLICATIONS OF PEGS

PEGs find extensive utilization in various fields due to their non-toxic nature. They are commonly employed in bioconjugation and surface modification activities, biomedical research, drug delivery, tissue engineering, and even in the food and cosmetics sectors. The process of attaching PEG polymer chains to molecules, either through covalent bonding or non-covalent means, is termed as PEGylation. This technique, known as PEGylation, can enhance the water compatibility and solubility of substances, bolster their stability and pharmacokinetic characteristics, and thereby amplify their safety and effectiveness in targeted drug delivery and diagnostics. PEG hydrogels are widely employed for precise therapeutic release, constructing matrices for cell cultures, promoting regenerative medicine, expediting wound healing, and contributing to tissue engineering.
