PEG can be synthesized via anionic polymerization of ethylene oxide and any hydroxyl initiators. Hydroxyl group could be from water or ethylene glycol or any diols. They can also be derived from ...

Polyethylene glycol is a high molecular polymer with the chemical formula HO(CH 2 CH 2 O) n H. It is non-irritating, has good water solubility, and has good compatibility with many organic components.

Biological drugs such as gene therapies and messenger RNA (mRNA) vaccines frequently rely on lipid nanoparticles (LNPs) coated in a layer of polyethylene glycol (PEG) to deliver medications to the ...

PEG, or polyethylene glycol, is a synthetically constructed polymer, made of repeating units of ethylene glycol (-CH 2-CH 2-O-). It is known for its properties of being water-soluble, as it is ...

Linking peptides to polyethylene glycol, or PEGylation, has helped improve pharmaceutical therapeutics in several ways. A wave of new techniques is now ushering in further advances. A number of ...
