“…1335 A parallel method permitted an antibiotic imprinted with dopamine to be used as recognition element. 1336 Mixing of imprinted polymer particles with carbon paste to generate moleculespecific electrodes offers another relatively simple route towards electrochemical sensors-this has been demonstrated by the research of Zeng and co-workers, who developed such mixed-material electrodes targeted towards a copper (II) dipyridyl complex, 979,980 and also by the work of Pizzariello et al 1337 in creating a clenbuterol-selective electrode. Sensors have also been created using this technique by Sode et al, [1338][1339][1340] based on amperometric sensing.…”

“…CV has been proved to be advantageous in characterizing quantum dots (QDs), particularly in terms of their stabilities in vivo [24]. CV has been shown to be effective in following molecular imprinting of copper complexes [25]. CV can also be used in tracing activated iridium oxide film (AIROF) microelectrode via the variation of scan rate during the steps of fabrications and animal implantation [26].…”

Cyclic voltammetry is a versatile method for scientific investigation and innovation due to the fact that most processes involve electron transfer, which makes them be able to be monitored by this technique. Its uses cover characterization, synthesis, mechanisms, and analysis. In all applications, the technique can work well with a large variety of compounds including organic, inorganic, polymer, films, and semiconductors, among others. Furthermore, the method operates satisfactorily whether in a direct or an indirect approach. It can be considered to be an essential part at the very beginning that leads further to the grand project. As an analytical tool, it plays an important role in not only chemistry but also other involving areas. This review sheds the light on the way the technique proves to become one of the important instruments in research, development, and application labs.

Electro-conductive hydrogels based on poly(vinyl alcohol), crosslinked with diethyl acetamidomalonate as the hydrogel component, were engineered using polyaniline as the inherently conductive component, and fabricated in the form of cylindrical devices to confer electro-actuable release of the model drug indomethacin. The hydrogels were characterized for their physicochemical and physicomechanical properties. Cyclic voltammetry was employed for electro-activity and conductivity analysis. Drug entrapment efficiency ranged from 65-70%. "ON-OFF" switchable drug release was obtained by periodically applying-removing-reapplying an electric potential ranging from 0.3-5.0 V for 60 seconds at hourly intervals and the cumulative drug release obtained ranged from 4.7-25.2% after four release cycles respectively. The electro-stimulated release of indomethacin was associated with the degree of crosslinking, the polymeric ratio and drug content. A Box-Behnken experimental design was constructed employing 1.2 V as the baseline potential difference. The devices demonstrated superior swellability and high OPEN ACCESSPolymers 2011, 3 151 diffusivity of indomethacin, in addition to high electrical conductivity with "ON-OFF" drug release kinetics via electrical switching. In order to investigate the electro-actuable release of indomethacin, molecular mechanics simulations using AMBER-force field were performed on systems containing water molecules and the poly(vinyl alcohol)-polyaniline composite under the influence of an external electric field. Various interaction energies were monitored to visualize the effect of the external electric field on the erosion of polyaniline from the co-polymeric matrix. This strategy allows the electro-conductive hydrogels to be suitably applied for controlled, local and electro-actuable drug release while sustaining a mild operating environment.
