This paper reports on a microfluidic impedimetric nitrate sensor using a graphene oxide (GO) nanosheets and poly(3,4-ethylenedioxythiophene) nanofibers (PEDOT-NFs) enabled electrochemical sensing interface. The sensor has demonstrated the ability to accurately detect and quantify nitrate ions in real samples extracted from soil. The PEDOT NFs-GO composite serves as an effective matrix for immobilization...
