摘要

将微加工技术与电化学传感器相结合，制成了一种新型的气体化学传感器。我们构建的微通道传感器由由纳米孔膜分隔的液/气微通道组成。当肟化学适用于微通道传感器时，它在~10秒内对化学战剂模拟物的痕量蒸汽(10 ppb)给出数百mV的响应。双微通道设计进一步减少了潜在的漂移并简化了传感器设置。

Microfabricated Electrochemical Sensor for Chemical Warfare Agents: Smaller is Better

A novel type of gas chemical sensor is fabricated by combining microfabrication techniques and electrochemical transducer. The microchannel sensor we built is composed of liquid/gas microchannels separated by a nanoporous membrane. When oxime chemistry is adapted into the microchannel sensor, it gives response of hundreds of mV to trace vapor (10 ppb) of chemical warfare agent simulants within ~10 sec. Double microchannel design further reduces potential drift and simplifies the sensor setup.
