Polydopamine has high adsorption capacities for pollutants such as pesticides in food and environmental matrices. Consequently, it has found applications in some sorbent-based micro-extraction techniques such as solid phase micro-extraction and magnetic solid phase extraction. This paper gives a detailed review of the application of polydopamine-based adsorbents for the extraction of pesticides in food and environmental matrices using these techniques. The adhesive properties of polydopamine have made it to be a suitable material for the immobilisation of the components of electrochemical sensors used to detect pesticides in food and environmental matrices. This paper also gives a comprehensive review on the application of polydopamine in electrochemical sensors such as acetylcholinesterase sensors, molecularly imprinted sensors and aptasensors. The use of polydopamine-based adsorbents during the extraction and electrochemical sensing of pesticides in food and environmental matrices is not free of challenges. In this review, the challenges encountered during the use of polydopamine-based adsorbents are also discussed.
聚多巴胺对食品和环境基质中的农药等污染物具有高吸附能力。因此，它已在一些基于吸附剂的微萃取技术中得到应用，如固相微萃取和磁性固相萃取。本文详细综述了基于聚多巴胺的吸附剂在使用这些技术提取食品和环境基质中农药的应用。聚多巴胺的粘附性能使其成为固定用于检测食品和环境基质中农药的电化学传感器组件的合适材料。本文还全面综述了聚多巴胺在电化学传感器中的应用，如乙酰胆碱酯酶传感器、分子印迹传感器和适体传感器。在食品和环境基质中农药的提取和电化学传感过程中使用基于聚多巴胺的吸附剂并非没有挑战。在本文中，还讨论了在使用基于聚多巴胺的吸附剂时遇到的挑战。
