Abstract A carbon fiber microelectrode (CFME) was coated with a polymeric film, in order to synthesize an MIP based voltammetric microsensor for the selective determination of DNOC. The polymeric synthesis was carried out by electrocopolymerization of aniline and o-phenylenediamine (o-PD) in a water:methanol (1:1) media. The response of the MIP-sensor synthesized to the target analyte, was linear in a range from 8 × 10−7 to 10−4 M with a sensitivity of 1.6 × 103 nA M−1 and good stability and repeatability (
