Superior Surface Protection of Gold Nanoparticles With Short-Chain PEG

Surface protection of gold nanoparticles is improved by using short-chain, alcohol-terminated dPEG® linkers rather than (2-mercaptopropanoyl)glycine (tiopronin) or mercapto-undecyl-tetraethyleneglycol, according to research findings from the lab of David E. Cliffel, Department of Chemistry, Vanderbilt University. Short-chain dPEG®s increase water solubility, are non-toxic, and show no immune response to anti-PEG antibodies at low concentrations.(1) Continue reading
