A new fluorescence switching sensor for sensitive detection of sinapine (SP) was developed based on aggregation and disaggregation of carbon quantum dots (CDs) with the assistance of copper ions (Cu2+). In the detection, carboxyl group on the surface of CDs enables the aggregation triggered by Cu2+ due to the effective coordination, inducing obvious fluorescence quenching. Upon the addition of SP...
Sinapine (SP) has attracted extensive attention in food and medical field because it is a crucial component in many plants with unique physiological activities. Here, we reported a fluorescent sensor based on the unique properties of graphene oxide (GO) for rapid, sensitive detection of SP concentration. In this strategy, GO has stronger affinity toward SP and can be also served as a quencher for...
