Description

Application

Diethylene glycol (diglycol) is used in biomaterials engineering to functionalize peptide nanofibers to improve their aggregation and proteolytic degradation properties. Diethylene glycol may be used as a solvent, reducing agent and derivatizing agent in the preparation of various types of nanoparticles.
