Decoration of glutathione with copper-platinum nanoparticles for chirality sensing of tyrosine enantiomers

Decoration of glutathione with copper-platinum nanoparticles for chirality sensing of tyrosine enantiomers

Cu and Pt nanoparticles (NPs) were simultaneously integrated with glutathione (GSH), and the resultant Cu-Pt NPs decorated GSH (GSH-Cu/Pt) was characterized by FT-IR and X-ray photoelectron spectroscopy (XPS). Next, the GSH-Cu/Pt was used for electrochemical chiral sensing of tyrosine (Tyr) enantiom...
