“…Cyclic voltammograms at 0.005 V s ( Fig. 1B) revealed the microelectrode behavior as presented in other studies (Choudhry et al, 2010a;Huang et al, 2009;Kadara et al, 2009b). Increasing the spray time had a significant reduction effect on the peak intensity and the peak-to-peak separation revealing that the cosmetic spray reduced the amount of accessible graphite ( Figs.…”

Disposable screen-printed electrodes (SPCE) were modified using a cosmetic product to partially block the electrode surface in order to obtain a microelectrode array. The microarrays formed were electropolymerized with aniline. Scanning electron microscopy was used to evaluate the modified and polymerized electrode surface. Electrochemical characteristics of the constructed sensor for cadmium analysis were evaluated by cyclic and square-wave voltammetry. Optimized stripping procedure in which the preconcentration of cadmium was achieved by depositing at -1.20 V (vs. Ag/AgCl) resulted in a well defined anodic peak at approximately -0.7 V at pH 4.6. The achieved limit of detection was 4 × 10 −9 mol dm −3. Spray modified and polymerized microarray electrodes were successfully applied to quantify cadmium in fish sample digests.

“…Microelectrodes have been fabricated using a variety of methods to produce different designs [2][3][4]. Our group has investigated the construction of microband devices which have been fabricated by covering the screen-printed carbon electrode (SPCE) working area with polyvinyl chloride (PVC) insulation tape, then cutting transversely across the centre of the working area [5,6].…”

“…Due to the different dimension of working gold electrodes, different cyclic voltammograms (CVs) and Nyquist diagrams of EIS were presented. As the electrode dimension reduced, the absolute current decreased while the corresponding resistance increased, which was attributed to the differential mass diffusion profiles 16. After modification with mercapto β‐CD, it can be observed that the electron‐transfer resistance ( R et,mod , semicircle domain in EIS) increased by different degrees in comparison with the 2 mm, 25 μm, and 400 nm diameter bare gold electrode, indicating that mercapto‐β‐CD SAMs had been decorated onto the working electrode surface.…”

An impedimetric sensor for persistent toxic substances, including organic pollutants and toxic inorganic ions is presented. The persistent toxic substances are detected using an ultrasensitive technique that is based on electron‐transfer blockage. This depends on the formation of guest–host complexes, hydrogen bonding, or a cyclodextrin (CD)‐metal complex (Mm(OH)n−β‐CD) structure between the target pollutants and β‐CD.
