A sensitive and simple flow injection chemiluminescence (CL) system was constructed for the determination of meropenem, in which the CL intensity of the KMnO-rhodamine B (Rh B) reaction was enhanced in the presence of CdS quantum dots (QDs). A CL resonance energy transfer (CRET) occurs between CdS QDs as a donor and Rh B as an energy acceptor. Based on the strong specific quenching effect of meropenem on the CL intensity, a novel chemosensor for meropenem sensing was developed. Under the optimized conditions, the quenched CL emission intensity was proportional to the concentration of meropenem in the range of 0.002-10.0 mg L with a detection limit (3σ) of 0.8 μg L Moreover, the feasibility of the induced CL system was studied via the meropenem determination in environmental water samples.
构建了一种灵敏且简单的流动注射化学发光（CL）体系用于美罗培南的测定，其中在硫化镉量子点（QDs）存在下，高锰酸钾 - 罗丹明B（Rh B）反应的CL强度增强。作为供体的硫化镉量子点与作为能量受体的罗丹明B之间发生了CL共振能量转移（CRET）。基于美罗培南对CL强度的强特异性猝灭作用，开发了一种用于美罗培南传感的新型化学传感器。在优化条件下，猝灭的CL发射强度与美罗培南浓度在0.002 - 10.0 mg/L范围内成正比，检测限（3σ）为0.8 μg/L。此外，通过测定环境水样中的美罗培南研究了该诱导CL体系的可行性。
