Homobifunctional PEG and Oligoethylene Glycols (84)

Homobifunctional polyethylene glycol is a PEG molecule containing two identical reactive groups, allowing it to create crosslinks or bonds with other molecules or materials. This makes it a common choice for developing multifunctional nanocarriers or crosslinked polymers. On the other hand, oligopolyethylene glycol (e.g., PEG-2 and PEG-4) primarily serves as a solvent and permeation enhancer, aiding in the dissolution of active ingredients, boosting stability and solubility, enhancing the permeability and absorption of oral drugs, and thereby increasing bioavailability.
