中文摘要:

      食品中兽药残留是引起食品安全的关键问题之一, 开发快速准确检测食品中兽药残留的方法势在必行。近年来, 为提高传感器的灵敏度和稳定性, 基于纳米材料的电分析生物传感器成为分析领域的热点。但目前绝大多数电化学生物传感器的研究还处于基础研究阶段。本文主要综述了基于纳米材料的电分析生物传感器在食品中兽药残留检测方面的研究和应用进展, 主要包括电化学生物传感器、电化学发光生物传感器和光电化学生物传感器。在采用近似的流程对同一种物质进行检测时, 光电化学方法获得的检测限通常比电化学方法低一个数量级。由于利用了电信号响应, 光电化学检测仪器设备简单、价格低廉且更易于微型化。

英文摘要:

      Veterinary drug residue in food is one of the key problems of causing food security, so development of rapid and accurate methods for the detection of veterinary drug residues in food is an inevitable trend. In recent years, nanomaterial-based electrochemical biosensors have attracted great attention in order to improve the sensitivity and stability of sensor. However, most of the electrochemical biosensors are still in the basic research stage at present. This article summarized the research progress on the detection of veterinary drug residues in food by nanomaterial-based electrochemical biosensors, including electrochemical biosensor, electrochemical luminescence biosensor and photoelectrochemical biosensor. The detection limit obtained by the photoelectrochemical method is usually lower than that of the electrochemical method when the approximate procedure is used to detect the same substance. Due to the use of electrical response, the photoelectrochemical device is simple, cheap and easy to miniaturization.
