TKACH, Volodymyr V.; NASCIMENTO, Hugo F.; NECHYPORUK, Vasyl´ V.  e  YAGODYNETS´, Petró I.. Mathematical description of the performance of pH-electrochemical sensors and biosensors, based on conducting polymers, on the pH-measurement of the liquid oral cavity operating at constant voltage. Rev. colomb. cienc. quim. farm. [online]. 2014, vol.43, n.1, pp.196-206. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v43n1.45473.

The work of pH-sensors and biosensors, based on conducting polymers, used in constant-voltage mode for mouth cavity pH-measurement, was mathematically described. By the analysis of the respective model, the best accuracy of the indicator, the steady-states´ multiplicity and oscillatory behavior conditions were derived.

Palavras-chave : hydrogen potential; electrochemical sensors; conducting polymers; oscillatory behavior; stable steady-state.
