Abstract
This Communication reports a novel colorimetric sensor to probe histidine in water based on para-sulfonatocalix[4]arene-modified silver nanoparticles; this highly selective sensor allows a rapid quantitative assay of histidine down to a concentration of 5 x 10(-6) M, providing a new tool for the direct measurement of histidine.
摘要
本通讯报道了一种基于对磺酸基杯[4]芳烃修饰的银纳米颗粒来探测水中组氨酸的新型比色传感器；这种高选择性传感器能够对低至5×10⁻⁶ M浓度的组氨酸进行快速定量测定，为组氨酸的直接测量提供了一种新工具。
