摘要：

In a previous work we have developed a biosensor able to detect the Sarin gas at a concentration of 0.1 mg/m3 with only 30 s of incubation time [1]. In this work, we modified the biosensor in order to integrate it into a miniaturized prototype. The prototype is composed of the cell in which is inserted the biosensor, a little fan able to sampling air and an electronic circuit. The circuit is able to apply the potential, to register the current, to turn on-off the fan and eventually give an alarm. The system was tested with paraoxon with satisfactory results.
