The method includes the steps that a certain amount of polyethylene glycol is dissolved into anhydrous organic solvent to prepare a solution, the appropriate amount of butyl titanate is evenly dispersed into the polyethylene glycol solution in an. 07) polymerizes, reacts with itself (in water), the reaction yields a variety of products containing varying numbers of ethylene glycol units. Polyethylene glycol (PEG) is made from ethylene glycol (ethane-1,2-diol), the main ingredient in antifreeze. By engineering a hierarchical polyethylene glycol (PEG) structure on nanoparticle surfaces, we revealed an alternative mechanism to enhance nanoparticle blood circulation. Before we address its popularity in industry, let's talk more about its structure. This page provides a brief introduction to the use and types of PEG reagents available to protein biology researchers. Especially in pharmaceutical research, PEG is used as a bioconjugate. Some relevant characteristics for its use in the biomedical field include solubility in water and organic solvents, controlled solubility, nontoxic, and hospitable to biological. Use in children less than 17 and chronic use is not approved by the FDA, but nevertheless the laxative is used as such in clinical practice.
