摘要
以香烟过滤嘴为原料,采用水热法制备碳量子点;基于多巴胺能猝灭碳量子点荧光的实验现象,发展了一种以碳量子点为荧光探针、在pH=8.0的磷酸盐缓冲溶液中测定多巴胺的分析方法,并探讨了荧光猝灭机理。在选定的实验条件下,当多巴胺浓度在1.2~84.0 μmol/L范围内时,荧光强度的猝灭值与浓度呈良好的线性关系,方法的检出限(3σ/k)为0.80 μmol/L。采用该方法对实际样品中的多巴胺进行测定,结果满意。
Abstract
Carbon quantum dots (CQDs) were prepared by hydrothermal treatment with cigarette filters as raw material. The results indicate that the fluorescence could be quenched by dopamine with high specificity. Based on this phenomenon, a fluorescence sensor was developed for the detection of dopamine in phosphate solutions (pH=8.0). Furthermore, the quenching mechanism of the CQDs was elucidated. The fluorescence quenching value showed linear responses with dopamine concentration ranging from 1.2 to 84.0 μmol/L with the detection limit of 0.80 μmol/L(3σ/k). Satisfactory results were achieved when the method was submitted to the determination of dopamine in real samples.
