Abstract
Competitive binding like that in immunoassays is the principle behind the chemosensor based on receptor 1, which was used to measure the concentration of citrate (2) in a series of common beverages. Citrate displaces the fluorescent colorimetric probe 5-carboxylfluorescein (3) from 1, and the process can be monitored by UV or fluorescence spectroscopy.
摘要
免疫分析中的竞争性结合是基于受体1的化学传感器的原理，该传感器用于测量一系列常见饮料中柠檬酸盐（2）的浓度。柠檬酸盐将荧光比色探针5-羧基荧光素（3）从1中置换出来，这一过程可以通过紫外光谱或荧光光谱进行监测。
