电化学/生物传感器快速检测大肠杆菌的研究进展

Development of rapid detection of escherichia coli by electrochemical sensor and biosensor

大肠杆菌广泛分布于自然界中,通常被用来作为水体系统排泄物污染情况的指示菌。它是大面积食物中毒的主要原因之一,严重感染者会引发败血症、肾功能衰竭等危及生命的并发症。电化学/生物传感器具有独特的优势,如能在浑浊溶液中操作、选择性好、灵敏度高、检测速度快等,因此在临床检测、环境保护和食品安全等领域得到了广泛应用。该文主要对电化学/生物传感器快速检测大肠杆菌的研究进展进行了简要的综述。

Escherichia coli （E. coli）, spreading abroad in natural environment, are commonly used as indicators of fecal contamination in water environments. They are one of the major causes of food-borne outbreaks and can produce life-threatening complications ranging from blood diarrhea to renal failure. Electrochemical sensors and biosensors have more advantages than other methods in that they can operate in turbid media and have good selectivity and high sensitivity. Therefore, they are applied widely in clinic diagnostics, environmental protection and food sanitation. This paper reviews briefly the recent development of rapid detection of E. coil by electrochemical sensors and biosensors.
