A highly sensitive electrochemiluminescence biosensor for the detection of organophosphate pesticides based on cyclodextrin functionalized graphitic carbon nitride and enzyme inhibition.
本文构建了一种信号开启型电化学发光(ECL)生物传感器,用于高灵敏检测有机磷农药(OPs)。该传感器以β-环糊精(CD)功能化石墨相氮化碳(g-C3N4)作为 ECL 发光体,利用 OPs 对乙酰胆碱酯酶(AChE)的抑制作用实现检测。CD 修饰可改善 g-C3N4 的分散性、亲水性和发光效率,并通过主客体识别包合羧基二茂铁(Fc-...
