一种双发射比率荧光探针的构建方法及其应用
摘要：
本发明公开了一种双发射比率荧光探针的构建方法，该方法通过将BPEI-CQDs碳量子点修饰在二氧化硅球上，操作简单、不需要复杂设备，所制备的双发射荧光探针(CdTe/CdS@SiO2@BPEI-CQDs)在苛刻条件下稳定性高；所建立的测定人体尿液中和血浆中微量Cu2+的方法选择性好、灵敏度高、可视化。
摘要（英）：

The invention discloses a building method of a double-emission-rate fluorescent probe. The building method has the advantages that BPEI-CQDs carbon quantum dots are used to modify silicon dioxide spheres, simple operation is achieved, complex equipment is not needed, and the built double-emission-rate fluorescent probe (CdTe/CdS@SiO2@BPEI-CQDs) is high in stability under harsh conditions; a built method for measuring trace Cu<2+> in human urine and plasma is good in selectivity, high in sensitivity and visual.
