Flow-through ordered macroporous silicon sensor for liquids detection

This paper has been devoted to a creation of flow-through sensor based on ordered macroporous silicon for electrophysical detection of liquids. Interactions of sensor with different liquids (deionized water, ethyl alcohol and sodium tetraborate in various concentrations) were studied by high frequency conductance measurements. It was established that the sensor had specific response for each liquid. It was shown that the proposed electrophysical method allowed identifying the liquid flowing through the sensor.
