摘要
本研究以银金属有机框架（AgMOF）和掺氮碳量子点（N-CDs）为基础，开发了一种新型电化学发光（ECL）传感器，用于高灵敏度地检测三氯铂（Tri）。氮掺杂碳量子点的 ECL 强度高，但 ECL 稳定性差，而银金属有机框架的比表面积大、孔隙率高、吸附性能好。二者的复合不仅提高了 N-CDs 的 ECL 稳定性，还增强了材料的 ECL 强度，因此 AgMOF@N-CDs 复合材料被用作传感器的发光体。在优化条件下，ECL 传感器检测 Tri 的线性范围为 1.0×10-7 M~1.0×10-3 M，检测限低至 5.99×10-8 M（信噪比=3）。此外，该传感器还具有良好的重现性、稳定性和抗干扰能力。该传感器可用于实际样品中 Tri 的检测，回收率在 95.78%~102.26% 之间，表明所构建的用于检测 Tri 的 ECL 传感器具有较好的应用前景。
A novel electrochemiluminescent sensor based on AgMOF@N-CD composites for sensitive detection of trilobatin†
In this study, a novel electrochemiluminescent (ECL) sensor for highly sensitive detection of trilobatin (Tri) was developed based on silver metal–organic frameworks (AgMOFs) and nitrogen-doped carbon quantum dots (N-CDs). N-CDs exhibited high ECL intensity but poor ECL stability, while AgMOFs had a large specific surface area, high porosity, and good adsorption properties. Compositing both of them not only improved the ECL stability of N-CDs, but also enhanced the ECL strength of materials, so AgMOF@N-CD composites were used as the luminophore of the sensor. Under the optimized conditions, the ECL sensor showed a linear range of 1.0 × 10−7 M to 1.0 × 10−3 M for the detection of Tri, and the detection limit was as low as 5.99 × 10−8 M (S/N = 3). In addition, the sensor had excellent reproducibility, stability, and anti-interference ability. It could be utilized for the detection of Tri in real samples with recoveries of 95.78–102.26%, indicating that the constructed ECL sensor for detecting Tri possessed better application prospects.
