The electroanalytical process is performed at the cathode, providing an efficient method. The analysis of the corresponding model, using linear stability theory and bifurcation analysis, has confirmed that the conducting polymer can serve as an efficient electrode modifier for the electrochemical determination of firocoxib. As for oscillatory and monotonic intabilities, they will depend on the nature of the monomer used to yield the conducting polymer. © 2025 by the authors.eninfo:eu-repo/semantics/closedAccessConducting PolymersElectrochemical OscillationsElectrochemical SensorsFirocoxibFood SecurityStable Steady-StateVeterinary DrugArticle
