Abstract
A phenanthroxazole-based fluorescent sensor for Cd(2+) has been developed. Of particular significance is the specific ratiometric response of the sensor toward Cd(2+) without interference from other biologically important metal ions including Zn(2+). The test paper made of this sensor exhibits both absorption and fluorescent color changes when exposed to Cd(2+) aqueous solution.
摘要
一种基于菲啰啉的荧光传感器已被开发用于检测 Cd(2+)。值得注意的是，该传感器对 Cd(2+)具有特异性的比率响应，不受包括 Zn(2+)在内的其他重要生物金属离子的干扰。由该传感器制成的检测试纸在接触 Cd(2+)水溶液时会发生吸收和荧光颜色变化。
