“…Wang et al [ 155 ] have utilized a similar method in developing the first electrochemical sensor for the detection of procainamide hydrochloride, a drug used for the treatment of cardiac arrhythmias. The sensor is based on a molecularly imprinted oligomeric methyl silsesquioxane (MSSQ) and TiO 2 composite sol coated GCE.…”

The oxides of transition, post-transition and rare-earth metals have a long history of robust and fast responsive recognition elements for electronic, optical, and gravimetric devices. A wide range of applications successfully utilized pristine or doped metal oxides and polymer-oxide hybrids as nanostructured recognition elements for the detection of biologically relevant molecules, harmful organic substances, and drugs as well as for the investigative process control applications. An overview of the selected recognition applications of molecularly imprinted sol-gel phases, metal oxides and hybrid nanomaterials composed of molecularly imprinted polymers (MIP) and metal oxides is presented herein. The formation and fabrication processes for imprinted sol-gel layers, metal oxides, MIP-coated oxide nanoparticles and other MIP/oxide nanohybrids are discussed along with their applications in monitoring bioorganic analytes and processes. The sensor characteristics such as dynamic detection range and limit of detection are compared as the performance criterion and the miniaturization and commercialization possibilities are critically discussed.

“…In recent years, usage of different electrochemical methods with various electrodes and modifiers has captured an additional interest of researchers due to speedy analysis, high sensitivity, selectivity, a high response of detection, repeatability and reproducibility, and also are less pricy. Only three reports [21][22][23] are found in the electrochemical study of PAH till date, amongst which one is from our research contribution itself. As per our literature survey, we found that there is no information regarding the electro-catalytic determination of PAH at the gold electrode.…”

The electrocatalytic oxidative behavior of an antiarrhythmic drug, procainamide hydrochloride (PAH) at the gold electrode surface has been examined using different voltammetric methods like cyclic, linear-sweep and differential pulse voltammetry. Voltammograms obtained in this study reveal that the electrode exhibit excellent electrocatalytic activity towards oxidation of the drug. The parameters that can affect the peak current at different pH, scan rate and concentration were evaluated. The number of electrons transferred was calculated. The current displayed a wide linear response ranging from 0.5 to 30.0 μM with a limit of detection of 56.4 nM. The impact of potential interfering agents was also studied. The electrode displayed wide advantages such as simple sample preparation, appreciable repeatability, reproducibility and also high sensitivity. Furthermore, the feasibility of the proposed method was successfully demonstrated by determining PAH in the spiked human biological sample.

Three-dimensional (3D) metal inorganics have gained tremendous interests for a series of applications. Here, we prepared TiO 2 microspheres, urchin-like TiO 2 , and flower-like TiO 2 by hydrothermal method. The morphologies of the three 3D TiO 2 nanostructures were characterized by scanning electron microscopy and X-ray diffraction analyses. The electrochemical behaviors of the 3D TiO 2 nanostructures were investigated by electrochemical impedance spectroscopy and cyclic voltammetry studies. Results showed that 3D TiO 2 -modified electrodes exhibited improved electrochemical performance compared with bare electrode. The three 3D nanostructures were then used with a modified glassy carbon electrode to detect dopamine (DA). According to the experimental results, the flower-like TiO 2 /GCE demonstrated excellent electrochemical performance than the two other electrodes. The enhanced electrochemical performance of the 3D flower-like TiO 2 /GCE is mainly affected by the structure of anatase crystal, which is the most important factor for the enhanced electrochemical performances toward DA detection. The flower-like TiO 2 /GCE, urchin-like TiO 2 /GCE, and TiO 2 microspheres/GCE possessed linear ranges of 0.02-160, 1-180, and 1-160 μM, with limit of detection values of 0.007, 0.31, and 0.33 μM, respectively.
