General description

Product is a thiolated carboxylic-polyethylene . 4α;-sulfanyl—ω carboxy PEG (HS–PEG–COOH) heterobifunctional PEGs with functional end-groups of very different reactivity. HS-PEG-COOH inhibits nonspecific binding to living cells.

Application

HS-PEG-COOH may be tethered to the gold nanoparticle end during the fabrication of epidermal growth factor (EGF)-conjugated surface-enhanced Raman spectroscopy (SERS) nanoparticles. HS-PEG-COOH was coated onto silicon-on-insulator photonic biosensor chips. Quantum dots (QD)/ virus-like particles (VLPs) could be obtained only from HS-PEG-COOH-coated QDs. It may be used to stabilize nanoparticles and prevent its aggregation.
Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
