Homobifunctional PEG and Oligoethylene Glycols (84)

Homobifunctional polyethylene glycol is a PEG molecule featuring two identical reactive groups, allowing it to create crosslinks or bonds with other molecules or materials. This property makes it ideal 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, facilitating the dissolution of active ingredients, boosting stability and solubility, increasing the permeability and absorption of oral drugs, and ultimately enhancing bioavailability.
