Detection of 1,3-dihydroxyacetone by tris(2,2′-bipyridine)ruthenium(II) electrochemiluminescence

Detection of 1,3-dihydroxyacetone by tris(2,2′-bipyridine)ruthenium(II) electrochemiluminescence 1,3-Dihydroxyacetone, a common cosmetic material and food additive, has been successfully explored as an efficient electrochemiluminescence coreactant of Ru(bpy)3 2+ 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analytical and Bioanalytical Chemistry Springer Journals

Abstract

1,3-Dihydroxyacetone, a common cosmetic material and food additive, has been successfully explored as an efficient electrochemiluminescence coreactant of Ru(bpy)3 2+ 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.
