1,3-Dihydroxyacetone, a common cosmetic material and food additive, has been successfully explored as an efficient electrochemiluminescence coreactant of Ru(bpy)₃²⁺ for the first time. It is about 25 times more effective than the well-known coreactant sodium oxalate. The high electrochemiluminescence efficiency allows sensitive detection of 1,3-dihydroxyacetone without any derivatization. The electrochemiluminescence method shows two linear electrochemiluminescence responses over the range of 5.0–500 μM and 500 μM–6.0 mM with a detection limit of 1.79 μM. The proposed method is at least two orders of magnitude more sensitive than other reported methods.

1,3-二羟基丙酮，一种常见的化妆品原料和食品添加剂，已成功地首次成功地作为Ru（bpy）₃ ^2+的一种有效的电化学发光共反应剂。它的效力是众所周知的共反应剂草酸钠的约25倍。高的化学发光效率允许灵敏地检测1,3-二羟基丙酮，而无需任何衍生作用。电化学发光方法在5.0–500μM和500 μM–6.0 mM的范围内显示出两个线性电化学发光响应，检出限为1.79μM。所提出的方法比其他报告的方法至少敏感两个数量级。
