SEN3: Potentiometric Nitrate Sensors in the Form of Plant Roots

Abstract

This work describes the development and testing of a sensitive and selective potentiometric nitrate microsensor that are scaleable to large, dense sensor networks required to study environmental systems. We have developed flexible, miniature and inexpensive nitrate sensors by electropolymerizing pyrrole onto carbon fiber substrates, using nitrate as a dopant. Carbon microfibers were found to be an excellent substitute to expensive conductive materials, such as glassy carbon or platinum.
