中文摘要 | the unique strategy for electrochemiluminescence (ecl) sensor based on the quantum dots (qds) oxidation in aqueous solution to detect amines is proposed for the first time. actually, there existed two qds ecl peaks in anhydrous solution, one at high positive potential and another at high negative potential. however, here we introduced the qds oxidation ecl in aqueous solution to fabricate a novel ecl sensor. such sensor needed only lower positive potential to produce ecl, which could prevent the interferences resulted from high potential as that of qds reduction ecl in aqueous solution. therefore, the present work not only extended the qds oxidation ecl application field from anhydrous to aqueous solution but also enriched the variety of ecl system in aqueous solution. furthermore, we investigated the qds oxidation ecl toward different kinds of amines, and found that both aliphatic alkyl and hydroxy groups could lead to the enhancement of ecl intensity. among these amines, 2-(dibutylamino)ethanol (dbae) is the most effective one, and accordingly, the first ecl sensing application of the qds oxidation ecl toward dbae is developed; the as-prepared ecl sensor shows wide linear range, high sensitivity, and good stability. |
