FIELD: electricity.
SUBSTANCE: electrochemical method for determination of gram-negative pathogenic bacteria in analysed medium suggests using as signal tag of electroactive magnet nanocomposite particles, which are produced before conjugation stage by creation of transition metals or their compounds for electroactive polymer coating on the surface of magnet nanoparticles. Concentration of pathogenic microorganisms is defined by electrochemical response registered directly in result of conversion of electroactive polymer coating.
EFFECT: analysis simplification, increased sensitivity, rapidness, reproducibility, widening the range of electrochemically active tags, using of polymer coating allows reaching high sensitivity and reproducibility of the analysis.
