摘　　要：食品中的生物污染和化学污染对食品安全的影响越来越明显,因此食品中污染物的检测方法及技术需要更高的要求。生物传感器是利用酶、免疫制剂、组织、细胞器或全细胞等生物识别元件的特异性生化反应,借助电、热、光等各种信号对生化物质进行检测的一类装置。主要阐述生物传感器在食品中致病菌、毒素、农药、重金属、非法添加物等污染物检测中的应用研究,并展望生物传感器在食品安全检测领域的研究重点和发展方向。Biological and chemical pollution in foodstuffs is becoming an increasingly important issue in the field of food safety. As a result, higher analytical requirements are needed for the detection of contaminants in foods. Biosensors are designed based on specific biochemical reactions mediated by isolated enzymes, immune preparations, tissues and organelles or whole cells to detect biological and chemical compounds usually by electrical, thermal or optical signals. Some recent applications of biosensors in the detection of containments in foods, such as microorganisms, toxins, pesticides, heavy metals and illegal additives are reviewed in this article. In addition, some key points and future trends in the application of biosensors for food safety detection are also discussed.
