摘要:
量子点传感器是基于荧光共振能量转移(FRET)等机理,对量子点进行功能修饰,构建用于化学污染物检测的传感器。功能化的量子点与污染物的特异性结合后,因荧光发生显著变化而实现检测目的,其具有响应快、效率高、可靠性强等特点,有助解决农产品快速检测仪存在的误检率高、专一性不强等不足。本文综述量子点传感器的制备、设计及在农产品化学污染物检测中的应用研究。

Abstract:
On the basis of the mechanism of Fluorescence resonance energy transfer, the quantum dots sensor is designed, synthesized and modified for detection of chemical pollutants.After the chemistry of the functionalized quantum dots and the chemical pollutant, the intensity of fluorescence decreased distinctly.The characteristics of fast response, high efficiency, reliable concerning the quantum dots sensor would solve the problems for the detection of the chemical pollutant in agro-product by the rapid detector.This article reviewed the design, synthesis and application of the quantum dots sensor for the quality control of the agro-products.
Key words:  Quantum dots sensor  design  chemical pollutants  detection
