Polyaniline and polypyrrole have been the most commonly used conjugated polymers for pathogen detection due to their high conductivity in the doped state (Kaur et al. 2015). Moreover, polypyrrole has been shown to be biocompatible and exhibit affinity for methylated nucleic acids (Arshak et al. 2009). However, polyaniline films lose electrochemical activity in solutions of pH greater than 4, which presents a measurement challenge when considering samples of varying pH (Wan, 2008). Conjugated polymer electrodes commonly exhibit thin-film form factors and are deposited onto insulating substrates via layer-by-layer approaches, spin coating, or electrochemical polymerization (Xia et al. 2010). For example, Chowdhury et al. used a polyaniline electrode for detection of E. coli over a dynamic range of 102 to 107 CFU/mL (Chowdhury et al. 2012). Hai et al. and He et al. used organic transistors based on spin-coated poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) films for detection of human influenza A virus (H1N1) and E. coli, respectively (Hai et al. 2018; He et al. 2012).
