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 TiO in this sensor improves the CT behavior and discrimination efficiency distinctly and enantiomeric discrimination is realized even at low concentration.
基于电荷转移（CT）诱导的表面增强拉曼散射（SERS）光谱，提出了一种具有手性信号放大功能的超高灵敏度传感器，用于各种氨基酸对映异构体的对映体识别。该传感器中引入的 TiO 可显著改善 CT 行为和识别效率，即使在低浓度下也能实现对映体的识别。
