A sensitive and selective fluorescence sensor for rutin was successfully developed. The sensor was fabricated from highly fluorescent nitrogen-boron co-doped carbon quantum dots (N,B-CDs) coated with mesoporous silica molecularly imprinted polymer (MIP). Rutin was detected by this sensor (N,B-CDs @ MIP) with a linear range of 0.08-30 μM and a detection limit as low as 0.05 μM, under optimal conditions. Meanwhile, the usefulness of the developed sensor was evaluated in samples of lake water, orange, and honey with satisfactory recoveries.
一种用于芦丁的灵敏且选择性的荧光传感器被成功研制出来。该传感器由涂有介孔二氧化硅分子印迹聚合物（MIP）的高荧光氮硼共掺杂碳量子点（N，B-CDs）制成。在最佳条件下，该传感器（N，B-CDs@MIP）对芦丁的检测线性范围为0.08 - 30 μM，检测限低至0.05 μM。同时，在湖水、橙子和蜂蜜样品中对所研制传感器的实用性进行了评估，回收率令人满意。
