摘要

本研究以谷胱甘肽（GSH）为还原剂和保护剂，制备了具有强荧光的铜银双金属纳米粒子（Cu/Ag BNPs）。GSH-Cu/Ag BNPs 对环境温度的荧光信号范围为 30 ∼ 90 °C，反应灵敏，可用作温度传感器。GSH-Cu/Ag BNPs 在 30 ℃ 左右的高荧光强度表明，Co 的检测不需要苛刻的温度条件，这为今后的实际检测工作提供了极大的便利。此外，Cu/Ag BNPs 中的谷胱甘肽以及 Cu/Ag BNPs 中 Cu 和 Ag 纳米粒子的协同效应可用作 Co 荧光检测的金属离子传感器。

Preparation of glutathione-Cu/Ag bimetallic nanoparticles for temperature and metal ion Co2+ sensing

In this work, copper silver bimetallic nanoparticles (Cu/Ag BNPs) with strong fluorescence were prepared using glutathione (GSH) as a reductant and protectant. The range of fluorescence signal of GSH-Cu/Ag BNPs to ambient temperature is 30∼90 °C has a sensitive response and can be used as a temperature sensor. The high fluorescence intensity of GSH-Cu/Ag BNPs at around 30 °C indicates that the detection of Co does not require harsh temperature conditions, which could be very convenient for future practical detection work. In addition, glutathione in Cu/Ag BNPs and the synergistic effect of Cu and Ag nanoparticles in Cu/Ag BNPs can be used as a metal ion sensor for Co fluorescence detection.
