For the immense requirement on agriculture and animal husbandry, application of pesticides and veterinary drugs had become a normal state in the farming and ranching areas. However, to intently pursue the yields, large quantities of residues of pesticides and veterinary drugs have caused serious harm to both the environment and the food industry. To control and solve such an issue, a variety of novel techniques were developed in recent years. In this review, the development and features about point-of-care-testing (POCT) detection on the residues of pesticides and veterinary drugs, such as, electrochemistry (EC), enzyme-linked immunosorbent assay (ELISA) and nano-techniques, were systematically introduced. For each topic, we first interpreted the strategies and detailed account of such technical contributions on detection and assessment of the residues. Finally, the advantages and perspectives about mentioned techniques for ultrasensitive assessment and sensing on pesticides and veterinary drugs were summarized.

由于对农业和畜牧业的巨大需求，农药和兽药的使用已成为农牧区的常态。然而，为了追求产量，大量的农药和兽药残留对环境和食品行业造成了严重危害。为了控制和解决这样的问题，近年来开发了多种新技术。在这篇综述中，电化学（EC）、酶联免疫吸附试验（ELISA）和纳米技术等农药和兽药残留的即时检测（POCT）检测的发展和特点，被系统地介绍。对于每个主题，我们首先解释了这些对残留物检测和评估的技术贡献的策略和详细说明。最后，总结了上述技术在农药和兽药超灵敏评估和传感方面的优势和前景。
