In this work, Waste pine nut shells were used as organic carbon source of biomass to synthesize carbon quantum dots. A highly responsive and selective fluorescent nanosensor (Si-doped biomass-derived carbon dots with molecular imprinted polymers, Si-CDs@MIPs) was designed for determination of Rutin (RT) in Chinese herbal substances like Sophora japonica L.. Not only was the synthesis method simple, environmentally friendly but also can selectively capture and specifically recognize the target compound RT, which was accomplished by a single-step hydrothermal process. The RT content in the real sample is 21%, with a recovery rate ranging from 89.7 to 106.3%, demonstrating excellent reproducibility. The nanosensor can selectively detect RT at a detection limit of 12.5 nmol/L. Therefore, it is showed that Si-CDs@MIPs will be feasible as a sensor for the rapid measurement of RT.
在本研究中，废弃松籽壳被用作生物质的有机碳源来合成碳量子点。设计了一种高响应性和选择性的荧光纳米传感器（具有分子印迹聚合物的硅掺杂生物质衍生碳点，Si-CDs@MIPs）用于测定诸如槐花等中草药中的芦丁（RT）。该合成方法不仅简单、环保，而且能够选择性地捕获并特异性识别目标化合物RT，这是通过一步水热法实现的。实际样品中的RT含量为21%，回收率在89.7%至106.3%之间，显示出优异的重现性。该纳米传感器能够以12.5 nmol/L的检测限选择性地检测RT。因此，表明Si-CDs@MIPs作为快速测定RT的传感器将是可行的。
