Yeast alcohol dehydrogenase can be used as a supramolecular assembly agent for fabricating image-containing luminescent materials towards solid-state electrochemiluminescene detection application

In this communication I report on a solution-based assembly strategy for the preparation of image-containing luminescent materials with the use of yeast alcohol dehydrogenase (YADH) as a supramolecular assembly agent, involving the direct mix of concentrated Ru(bpy)3Cl2 and YADH aqueous solutions at room temperature. It is unexpectedly found that the resulting assemblies can form very stable film on bare electrode surfaces and at the same time exhibit excellent electrochemiluminescene (ECL) behaviors and therefore, provide us a novel kind of easily-immobilized luminescent materials for solid-state ECL detection in capillary electrophoresis (CE) or CE microchip.
