Capsulation of AuNCs with AIE Effect into Metal-Organic Framework for the Marriage of a Fluorescence and Colorimetric Biosensor to Detect Organophosphorus Pesticides.
有机磷农药(OPs)可抑制乙酰胆碱酯酶(AChE)活性并诱发神经系统疾病,因此需要快速、灵敏的监测方法。本文以金属有机框架(MOF)为载体原位包裹金纳米簇(AuNCs),利用ZIF-8对AuNCs分子运动的限域作用触发聚集诱导发光(AIE)效应,使AuNCs@ZIF-8具有强荧光,荧光寿命和量子产率分别为6.83 μs和4.63%。...
