eng Electrochemical properties of screen-printed sensors with chemically deposited boron doped diamond electrode and their applications in electroanalysis The boron doped diamond electrode (BDDE) currently has been firmly established in the field of electroanalytical chemistry due to its excellent properties such as wide available potential window, low background current, low current noise, good chemical resistance, resistance to passivation and high mechanical stability [1]. In recent years, the trend towards miniaturization, acceleration of the analysis and cheapening has increased which brings the development of new types of electrodes and sensors, including printed sensors. Their main advantage consists in their low price and possibility of easy mass production, thanks to which they can be used as disposable sensors [2]. Therefore, the screen-printed (SP) sensors with chemical deposited BDDE as a working electrode (SP/BDDE) can be perspective alternative to bulk BDDE in the field of electroanalysis. The subject of this work is the investigation of the electrochemical properties of newly prepared SP/BDDE and their comparison with commercially available printed sensors and bulk BDDE. For these studies mainly cyclic voltammetry of reversible redox systems ([Fe(CN6)]4−/3− and [Ru(NH3)6]3+/2+) was used. In addition to the width of the potential window, the difference between the potentials of the anodic and cathodic peaks and the ratios of their heights were also compared. Other parameters tested were repeatability and reproducibility of measurements both at one electrode and between electrodes. This work also shows the applicability of new tested sensors in the analysis of various compounds important environmentally (pesticides) and in term of human health (drugs).
