eng Screen-printed sensors with chemically deposited boron-doped diamond electrode: the effect of the ratio of the area of the working to the auxiliary electrode. The subject of this work was the study of the effect of the ratio of the areas of the working to the auxiliary electrodes of screen-printed sensors with a chemically deposited boron diamond electrode (BDDE) on their electrochemical properties and applicability. Three different ratios of 0.9, 0.4, and 0.1 were studied. Using conventional redox markers ([Fe(CN)6]4−/3−, [Ru(NH3)6]2+/3+, and dopamine), the electrochemical properties of these sensors were compared based on the evaluation of the parameters of the obtained cyclic voltammograms. The influence of the area ratio of working to auxiliary electrodes on the analysis of 2,6-dichlorophenol was also investigated.
