Chemically modified CdSe/ZnS quantum dots (QDs) are used as fluorescent probes for the analysis of explosives, and specifically, the detection of trinitrotoluene (TNT) or trinitrotriazine (RDX). The QDs are functionalized with electron-donating ligands that bind nitro-containing explosives, exhibiting electron-acceptor properties, to the QD surface, via supramolecular donor-acceptor interactions leading to the quenching of the luminescence of the QDs.
化学修饰的 CdSe/ZnS 量子点 (QDs) 可用作荧光探针来分析爆炸物，特别是检测三硝基甲苯 (TNT) 或三硝基三嗪 (RDX)。量子点通过超分子供体-受体相互作用进行功能化，与含硝基的爆炸物结合，表面表现出电子受体特性，从而导致量子点的发光猝灭。
