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) enantiomers, and the results show that the recognition efficiency, indicated by peak current ratio of L-Tyr to D-Tyr and peak potential separation, of the GSH-Cu/Pt is superior to those of GSH, Cu NPs decorated GSH (GSH-Cu) and Pt NPs decorated GSH (GSH-Pt). The higher affinity of GSH-Cu/Pt to L-Tyr than D-Tyr is further confirmed by density functional theory (DFT) and UV spectra.

Cu和Pt纳米粒子（NPs）同时与谷胱甘肽（GSH）整合，并通过FT-IR和X射线光电子能谱（XPS）对得到的装饰有GSH的Cu-Pt NPs（GSH-Cu / Pt）进行表征。然后，将GSH-Cu / Pt用于酪氨酸（Tyr）对映体的电化学手性检测，结果表明，识别效率由L-Tyr与D-Tyr的峰电流比和峰电势分离表示。 GSH-Cu / Pt优于GSH，装饰有GSH的Cu NPs（GSH-Cu）和装饰有GSH的Pt NPs（GSH-Pt）。密度泛函理论（DFT）和紫外光谱进一步证实了GSH-Cu / Pt对L-Tyr的亲和力高于D-Tyr。
