The most efficient and commonly used electrochemiluminescence (ECL) emitters are luminol, [Ru(bpy)3]2+, and derivatives thereof. Luminol stands out due to its low excitation potential, but applications are limited by its insolubility under physiological conditions. The water‐soluble m‐carboxy luminol was synthesized in 15 % yield and exhibited high solubility under physiological conditions and afforded
最有效和最常用的电化学发光(ECL)发射器是鲁米诺,[Ru(bpy)3 ] 2+及其衍生物。鲁米诺因其激发电势低而脱颖而出,但其应用受到其在生理条件下的不溶性限制。水溶性米羧基鲁米诺在15%的产率合成并在生理条件下表现出高溶解性,可以得到4倍的ECL信号增加(相对于鲁米诺)。包裹在带有DNA标记的脂质体中的DNA检出限为3.2 pmol L -1,比相应的荧光方法低150倍。这种非凡的灵敏度增益和低激励电位建立了m‐羧基鲁米诺是一种优异的ECL探针,与化学发光和酶促生物分析方法直接相关。
