Abstract

In this study, a convenient and sensitive method for the detection of resveratrol was established based on phosphorescence quenching of resveratrol for MPA-capped Mn:ZnS QDs. The quenching intensity was in proportion to the concentration of resveratrol within a certain range. Under optimal conditions, the present assay was valid for detecting resveratrol in the range from 0.03 μM to 14 μM with a detection limit of 0.01 μM. The mechanism of action was also explored, and its application in actual samples was also demonstrated with satisfactory results. This study aims to provide a convenient method for the detection of resveratrol.

摘要

在本研究中，基于白藜芦醇对MPA包覆的Mn:ZnS量子点的磷光猝灭，建立了一种简便灵敏的白藜芦醇检测方法。在一定范围内，猝灭强度与白藜芦醇浓度成正比。在最佳条件下，本测定法可有效检测0.03 μM至14 μM范围内的白藜芦醇，检测限为0.01 μM。还探讨了其作用机制，并展示了其在实际样品中的应用，结果令人满意。本研究旨在提供一种简便的白藜芦醇检测方法。
