This work describes the way of sensing bacteria, Legionella by photogate‐type fluorescence sensor. Photoirradiation time dependences of L. dumoffii with the UV‐photointensity as a parameter was obtained by the optical sensor. The photocurrents obtained by the sensor decreased depending on the irradiation time, showing the decay process of fluorescent material in Legionella cells. Initial decay rates were also found to vary with UV‐photointensity. These results indicate that the photogate‐type optical sensor can detect Legionella by using a simple combination of photochemical reaction rate constant and the excitation light intensity.

通过光电门型荧光传感器感应军团菌

这项工作描述了通过光门型荧光传感器检测细菌军团菌的方法。通过光学传感器获得了以紫外线光强度为参数的杜氏乳杆菌的光照射时间依赖性。传感器获得的光电流根据照射时间而减少，表明退伍军人病菌细胞中荧光物质的衰减过程。还发现初始衰减率随紫外线强度而变化。这些结果表明，光门型光学传感器可以通过简单地将光化学反应速率常数和激发光强度结合在一起来检测军团菌。
