“…Carbon paste-based electrodes, which are employed for sensing and detecting analytes in concern, have quickly become popular in electrochemical and electroanalytical studies and they are the most preferred electrode materials that can be designed in labs without requiring special equipment [19]. The advantages of carbon paste electrodes are their cheapness, easier manufacture, high detection sensitivity, and surface renewability [20].…”

“…Conventionally, the first basic ingredient of a carbon paste is carbon powder, i. e. highly pure graphite, typically with a particle size of micrometers or tens of micrometers. The second component of carbon paste mixes is traditional binders (1) mineral/paraffin oils, predominantly silicone fluids such as Nujol ® , or (2) macromolecular alkyl siloxanes [19].…”

This study developed a nanosensor for the detection and determination of favipiravir, a presumed drug that has potential therapeutic efficacy in treating COVID‐19 patients, from tablets and serum samples. This nanosensor was obtained by adding the optimum amount of diamond nanoparticles into carbon paste. For the determination of favipiravir adsorptive stripping differential pulse (AdSDPV) and adsorptive stripping square wave voltammetry (AdSSWV) were used. Limit of detection values were found as 4.83×10−9 M and 2.44×10−7 M for bulk and 5.18×10−8 M and 4.38×10−8 M for serum samples using AdSDPV and AdSSWV, respectively. Recovery studies made of the tablet and serum produced satisfactory results.

“…Nevertheless, increasing the amount of binder to 35% at a ratio of 65/35 resulted in a sharp drop in the recorded I pa , which may be attributed to the increased resistivity of the modified electrode. The results show that the minimum and adequate amount of paraffin oil as binder should be used, as the inherent nonconductivity feature of paraffin oil can reduce the electrochemical performance of the paste electrode . Therefore, 20% binder was selected as the optimum content level for the fabrication of the optimized sensor.…”

Grinding the mixture into a uniform paste for up to 40 CV measurements were employed to evaluate the catalytic performance of the fabricated electrodes toward glucose oxidation.…”

The design of sensitive and cost-effective biocomposite materials with high catalytic activity for the effective electrooxidation of glucose plays a key role in developing enzyme-free glucose sensors. The porous three-dimensional (3D) spongin scaffold of marine sponge origin provides an excellent template for the growth of atacamite crystals and improves the activity of atacamite as a catalyst. By using the design of experiment method, the influence of different parameters on the electrode efficiency was optimized. The optimized sensor based on spongin–atacamite showed distinguished performance toward glucose with two linear ranges of 0.4–200 μM and 0.2–10 mM and high sensitivities of 3908.4 and 600.5 μA mM–1 cm–2, respectively. Importantly, the designed sensor exhibited strong selectivity and favorable stability, reproducibility, and repeatability. The performance in the real application was estimated by glucose detection in spiked human blood serum samples, which verified its great potential as a reliable platform for enzyme-free glucose sensing.

“…), and a binding agent (e.g., mineral oil, paraffin oil). In the composite, the ratio of the modifier may vary, and usually, big amounts of modifier in the composite could decrease the catalytic activity and the electron transfer; therefore, researchers evaluate the different proportions to find the best electrochemical response [11][12][13].…”

Metalloporphyrins (MP) and metallophtalocyanines (MPc) are innovative materials with catalytic properties that have attracted attention for their application for diverse electrochemical purposes. The presence of metallic centers in their structure offers a redox-active behavior that is being applied in the design of solid electrodes for the quantification of biomolecules, water contaminants, and pharmaceuticals, among others. Herein, we collect the recent information about porphyrin and phthalocyanine complexes as modifiers of electrodes, and the important aspects of the design, characterization, and application of these electrodes.
