Abstract

Pesticides are among the most important contaminants in food, leading to important global health problems. While conventional techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry (MS) have traditionally been utilized for the detection of such food contaminants, they are relatively expensive, time-consuming and labor intensive, limiting their use for point-of-care (POC) applications. Electrochemical (bio)sensors are emerging devices meeting such expectations, since they represent reliable, simple, cheap, portable, selective and easy to use analytical tools that can be used outside the laboratories by non-specialized personnel. Screen-printed electrodes (SPEs) stand out from the variety of transducers used in electrochemical (bio)sensing because of their small size, high integration, low cost and ability to measure in few microliters of sample. In this context, in this review article, we summarize and discuss about the use of SPEs as analytical tools in the development of (bio)sensors for pesticides of interest for food control. Finally, aspects related to the analytical performance of the developed (bio)sensors together with prospects for future improvements are discussed.

摘要

农药是食品中最重要的污染物之一,导致了重要的全球健康问题。虽然传统的技术,如高效液相色谱法(HPLC)和质谱法(MS),通常用于检测此类食品污染物,但它们相对昂贵、耗时且劳动强度大,限制了它们在即时检测(POC)应用中的使用。电化学(生物)传感器是满足这些期望的新兴设备,因为它们是可靠、简单、廉价、便携、选择性和易于使用的分析工具,可以由非专业人员在实验室外使用。由于其尺寸小、集成度高、成本低和能够测量几微升样品的能力,丝网印刷电极(SPE)在电化学(生物)传感中使用的各种传感器中脱颖而出。在这方面,在这篇综述文章中,我们总结和讨论了 SPE 作为分析工具在用于食品控制的感兴趣农药的(生物)传感器开发中的应用。最后,讨论了开发的(生物)传感器的分析性能以及未来改进的前景。
