本综述（参考文献114篇）涵盖了2010年至2015年在食品中农药的纳米材料电化学生物传感器领域取得的进展。它的主要重点是分析真实的样本的策略。本文首先简要介绍了最常用的生物识别元件。这些包括（a）酶（产生基于抑制和直接催化的生物传感器），（B）抗体（产生免疫传感器），和（c）适体（产生适体传感器）。下一个主要部分涵盖了用于生物传感器的各种纳米材料，包括碳质物质（碳纳米管，石墨烯，炭黑等），以及纳米颗粒，棒或多孔材料形式的非碳质物质。样品处理和真实的样品分析方面的处理，然后讨论在定制的食品分析的先进技术。
This overview (with 114 refs.) covers the progress made between 2010 and 2015 in the field of nanomaterial based electrochemical biosensors for pesticides in food. Its main focus is on strategies to analyze real samples. The review first gives a short introduction into the most often used biorecognition elements. These include (a) enzymes (resulting in inhibition-based and direct catalytic biosensors), (b) antibodies (resulting in immunosensors), and (c) aptamers (resulting in aptasensors). The next main section covers the various kinds of nanomaterials for use in biosensors and includes carbonaceous species (carbon nanotubes, graphene, carbon black and others), and non-carbonaceous species in the form of nanoparticles, rods, or porous materials. Aspects of sample treatment and real sample analysis are treated next before discussing vanguard technologies in tailor-made food analysis.
