This article presents the development of an electrochemical biosensor based on conductive polymers and microorganisms for rapid and sensitive detection of surfactants in aqueous media. The study includes a systematic comparative investigation of several conductive polymers (poly(neutral red) pNR, poly(thionine) pTN, polypyrrole PPy, polyaniline PANI, and PEDOT:PSS) and selection of the optimal conductive polymer (pNR) and microorganism (Pseudomonas putida VKM B-973) as well as investigation of their interaction rates and electrochemical properties. Modification of electrodes with carbon nanomaterials such as single-walled carbon nanotubes (SWCNT) has been shown to significantly improve the sensitivity (lower limit of detectable concentration is 0.061 mg/dm3) and stability (microbial sensor can function for 15 days with relative standard deviation of analytical signal being 5.4 %) of the biosensor. The device is used for detecting anionic surfactant in river water samples and the results obtained are statistically insignificant from those obtained by the conventional method of analysis.
