A mixture of the Pd(II) complex [Pd(NO(3))(2)(bipy)] (bipy = 2,2'-bipyridine) and the fluorescent dye Methylcalcein blue (MCB) constitutes a chemosensing ensemble which can be used for the detection of pyrophosphate (PPi) by fluorescence spectroscopy. The sensor operates in buffered aqueous solution at neutral pH, and allows sensing PPi at low to mid micromolar concentrations with very good selectivity over other anions such as phosphate, acetate, nitrate, sulfate, chloride, and bicarbonate.
Pd(II) 配合物[Pd(NO(3))(2)(bipy)]（bipy = 2,2'-联吡啶）和荧光染料 Methylcalcein blue（MCB）的混合物构成了一个化学感应组件，可通过荧光光谱法检测焦磷酸盐（PPi）。该传感器在中性 pH 的缓冲水溶液中运行，可在低至中微摩尔浓度下检测 PPi，对其他阴离子如磷酸盐、醋酸盐、硝酸盐、硫酸盐、氯化物和碳酸氢盐具有非常好的选择性。
