Microbial potentiometric sensor array measurements in unsaturated soils

Review—Recent Advances in Sensor Arrays for the Simultaneous Electrochemical Detection of Multiple Analytes

“…Burge et al presented a microbial potentiometric sensor (MPS) array for potential measurements generated by plants and microorganisms in unsaturated soils. 56 The MPS array was composed of 24 carbon electrodes including two reference electrodes made of coated platinum carbon fabric. While half of the carbon fabric was exposed to the atmosphere, the other half was placed to the soil profile.…”
