Dual screen-printed electrodes with elliptic working electrodes arranged in parallel or perpendicular to the strip

The number of works based on electrochemical mono-, bi- and multi-sensors is increasing, especially in which multiplexing is concerning. Determination of a panel of analytes in clinical analysis or of different related molecules in environmental or food analysis has increased the efforts for designi...

520			\|a The number of works based on electrochemical mono-, bi- and multi-sensors is increasing, especially in which multiplexing is concerning. Determination of a panel of analytes in clinical analysis or of different related molecules in environmental or food analysis has increased the efforts for designing appropriate sensors, becoming the design, a very important step in their development. In this paper, two different dual designs for screen-printed electrodes, one of them symmetrical, were electrochemically evaluated with methylene blue as electroactive species. Two elliptic working electrodes substituted the traditional circled and centered working electrodes in the monosensing mode. Ellipses perpendicular to the strip and with the same configuration than conventional for reference and auxiliary electrodes constituted the asymmetrical design. Placing the ellipses in parallel with the strip, surrounding them with a counter electrode and locating the reference at the basis, produces a symmetrical design. Although both could be employed, more precise peak intensities are obtained for the more symmetrical design as well as with the employ of an external reference and auxiliary electrode system. Since a more sensitive detection is increasingly required, comparison is made also after nanostructuration with carbon nanotubes. The symmetrical design appears also to be more appropriate for all the electrochemical techniques tested: cyclic voltammetry, differential pulse voltammetry and square wave voltammetry.

Determination of a panel of analytes in clinical analysis or of different related molecules in environmental or food analysis has increased the efforts for designing appropriate sensors, becoming the design, a very important step in their development. In this paper, two different dual designs for screen-printed electrodes, one of them symmetrical, were electrochemically evaluated with methylene blue as electroactive species. Two elliptic working electrodes substituted the traditional circled and centered working electrodes in the monosensing mode. Ellipses perpendicular to the strip and with the same configuration than conventional for reference and auxiliary electrodes constituted the asymmetrical design. Placing the ellipses in parallel with the strip, surrounding them with a counter electrode and locating the reference at the basis, produces a symmetrical design. Although both could be employed, more precise peak intensities are obtained for the more symmetrical design as well as with the employ of an external reference and auxiliary electrode system. Since a more sensitive detection is increasingly required, comparison is made also after nanostructuration with carbon nanotubes. The symmetrical design appears also to be more appropriate for all the electrochemical techniques tested: cyclic voltammetry, differential pulse voltammetry and square wave voltammetry.

abstract	The number of works based on electrochemical mono-, bi- and multi-sensors is increasing, especially in which multiplexing is concerning. Determination of a panel of analytes in clinical analysis or of different related molecules in environmental or food analysis has increased the efforts for designing appropriate sensors, becoming the design, a very important step in their development. In this paper, two different dual designs for screen-printed electrodes, one of them symmetrical, were electrochemically evaluated with methylene blue as electroactive species. Two elliptic working electrodes substituted the traditional circled and centered working electrodes in the monosensing mode. Ellipses perpendicular to the strip and with the same configuration than conventional for reference and auxiliary electrodes constituted the asymmetrical design. Placing the ellipses in parallel with the strip, surrounding them with a counter electrode and locating the reference at the basis, produces a symmetrical design. Although both could be employed, more precise peak intensities are obtained for the more symmetrical design as well as with the employ of an external reference and auxiliary electrode system. Since a more sensitive detection is increasingly required, comparison is made also after nanostructuration with carbon nanotubes. The symmetrical design appears also to be more appropriate for all the electrochemical techniques tested: cyclic voltammetry, differential pulse voltammetry and square wave voltammetry.
