TKACH, Volodymyr Valentynovych; NECHYPORUK, Vasyl´ Vasyl´ovych  and  YAGODYNETS´, Petro Ivanonych. The mathematical description for the process of the detection of two substances with a common functional group by cp-based sensors and biosensors. Rev. colomb. cienc. quim. farm. [online]. 2013, vol.42, n.2, pp.215-225. ISSN 0034-7418.

The behavior of the electrochemical sensors and biosensors, based on conducting polymers (cp) in the detection process for two substances with a common functional group has been described mathematically and the respective model was analyzed by the linear stability theory and bifurcational analysis. The conditions for the stability of the steady-state, for the oscillatory and monotonic instability have been inferred. The connection between the present model and the yet described has been shown.

Keywords : functional group; organic analysis; electrochemical sensors; conducting polymers; stable steady-state.
