This review focuses on the ways in which screen-printed carbon electrodes have been tailored with different biorecognition elements, including enzymes, antibodies, and aptamers, often with other modifiers, such as mediators and nanoparticles, to produce electrochemical biosensors for a variety of analytes of importance in agri-food safety. Emphasis is placed on the strategies of biosensor fabrication and the performance characteristics of the devices. As well as biosensors for a range of analytes in different agri-food matrices, we have also included reports on novel devices that have potential in agri-food safety but as yet have not been applied in this area.

这篇综述着重于如何用不同的生物识别元件（包括酶，抗体和适体，通常与其他修饰剂，例如介体和纳米颗粒）定制丝网印刷碳电极的方法，以生产用于多种分析物的电化学生物传感器。在农业食品安全中的重要性。重点放在生物传感器的制造策略和设备的性能特征上。除了可用于各种农业食品基质中各种分析物的生物传感器外，我们还提供了有关新型设备的报告，这些设备在农业食品安全方面具有潜力，但尚未在该领域中得到应用。
