  A detection system for anaerobic micro-organisms involves the addition to a nutrient medium (2) for the micro-organisms of an indicator species which is electrochemically reducible, soluble in the nutrient medium and consumed by the micro-organisms during growth. Two electrodes (3,4) are immersed in the nutrient medium and changes in an electrical property of the nutrient medium are monitored. A preferred indicator species is riboflavin.

  厌氧微生物的检测系统是在微生物的营养介质（2）中加入一种指示剂，这种指示剂具有电化学还原性，可溶于营养介质，并在生长过程中被微生物消耗。两个电极（3、4）浸入营养介质中，监测营养介质电特性的变化。首选的指示剂是核黄素。

  Disclosed herein are methods and devices for detecting the presence of an analyte of interest. A biosensor device can include a reaction chamber and an electrochemical detection chamber. The reaction chamber can include at least one immobilized binding site and a probe conjugate adapted to bind to at least one of the target analyte and the immobilized binding site, while the detection chamber can include electrodes for detecting an electrochemical reaction. If present, the target analyte in the fluid sample results in a change in the amount of probe conjugate bound in the reaction chamber, which can be detected electrochemically in the detection chamber.

  本文公开了用于检测相关分析物存在的方法和装置。生物传感器装置可包括反应室和电化学检测室。反应室可包括至少一个固定结合位点和适于与目标分析物和固定结合位点中的至少一个结合的探针共轭物，而检测室可包括用于检测电化学反应的电极。如果存在，流体样品中的目标分析物会导致反应室中结合的探针共轭物的量发生变化，这种变化可在检测室中通过电化学方法进行检测。
