Abstract

Abstract : An ultra-high sensitivity enantioselective sensor with excellent discrimination performance for trace amino acids by using charge transfer-induced SERS. Abstract : An ultra-high sensitivity sensor with the function of chiral signal amplification has been proposed for the enantiomer discrimination of various amino acid enantiomers based on charge transfer (CT)-induced SERS spectroscopy. The introduced TiO2 in this sensor improves the CT behavior and discrimination efficiency distinctly and enantiomeric discrimination is realized even at low concentration.
