Stability study in the performance of sensors and biosensors based on conductor polymers in strong acidic media

Developing and constructing the mathematical model (applying the linear stability theory and bifurcation analysis), the electrochemical behavior, observed during the work of the CP-based electrochemical sensors and biosensors in strongly acid solution, was investigated. The conditions for the steady...

The conditions for the steady-state stability and oscillatory and monotonic instabilities were derived for the work of the biosensor in potentiostatic mode. The results of the analysis for the case of strongly acid solution were compared to the previously obtained for the case of neutral and basic solution and in such way it's possible to make conclusions about the influence of pH on the functioning of sensors and biosensors.Por medio del desarrollo del modelo matemático y su análisis (aplicándose la teoría de estabilidad lineal y el análisis de bifurcaciones) se investigó el comportamiento electroquímico, observado en el caso del desempeño de los sensores y biosensores electroquímicos basados en los polímeros conductores en una solución altamente ácida. Fueron derivadas las condiciones de estabilidad del estado estacionario; de las inestabilidades oscilatorias y monotónicas para el desempeño del biosensor en modo de potencia estática. Los resultados del análisis para el caso del medio fuertemente ácido se compararon con los anteriormente obtenidos para el de la solución neutral y básica; por lo cual, así pudo ser inferida la conclusión sobre la influencia del pH al funcionamiento de los sensores y biosensores electroquímicos.application/pdfspaRevista Colombiana de Ciencias Químico Farmacéuticashttp://revistas.unal.edu.co/index.php/rccquifa/article/view/45101Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de Ciencias Químico FarmacéuticasRevista Colombiana de Ciencias Químico FarmacéuticasRevista Colombiana de Ciencias Químico Farmacéuticas; Vol. 42, núm. 1 (2013); 30-41 0034-7418 1909-6356Valentynovych Tkach, Volodymyr and Vasyl´ovych Nechyporuk, Vasyl´ and Ivanonych Yagodynets´, Petro (2013) Stability study in the performance of sensors and biosensors based on conductor polymers in strong acidic media.
