“…The calibration plot shown in Figure b shows the correlation coefficient of lower concentration of I pa , R 2 = 0.991, and higher concentration of I pa , R 2 = 0.9965. Based on eq the limit of detection (LOD) was calculated: − LOD = 3 σ / S where S is the slope from the linear range and σ indicates the deviation of the blank (S/N = 3). The LOD was estimated using this equation and was found to be 2.1 nM.…”

Electrochemical applications such as electrical conductivity, sensitivity, selectivity, cost-effectiveness, and sampling techniques of different forms of pyrochlore oxide have been a field of current interest. In this regard, pyrochlore structured lanthanum stannate nanoparticles (LSO) decorated with functionalized halloysite nanotubes (f-HNT) were prepared via hydrothermal followed by sonochemical synthesis. The obtained samples were characterized through various spectroscopic and microscopic methods to investigate the LSO@f-HNT structure and morphology. Electrocatalytic studies of LSO@f-HNT were performed by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The beneficial response of LSO interacting with the hollow structured f-HNT groups of aluminol (Al−OH) and siloxane (Si−O−Si) enhances the electron transmission channel and active site size, both of which contribute to improved electrocatalytic performance. The fabricated sustainable LSO@f-HNT electrocatalyst exhibits outstanding selectivity and linear range (0.01−480 μM) with a detection limit of 2.1 nM and produces good recovery results (97.8−99.68%) under the optimized measurement conditions. This study discusses the design of the LSO@f-HNT composite and its application as an electrode material for the sensitive and focused electrochemical detection of hazardous Metol. This research demonstrates that LSO and f-HNT

“…A couple from the glassy electrode series were modified using boron nitride (BN) with bismuth sulfide (Bi 2 S 3 ) or titanium carbide (TiC). 102,105 Most glassy carbon based electrodes were modified with binary metal oxides nanoparticles such as lanthanum cerate (LaCe NPs), gadolinium vanadate (GdVO 4 ), zinc manganite (ZnMn 2 O 4 ), and samarium vanadate (SmV) with or without carbon-based nanomaterials like carbon nanofibers (CNF) and graphene oxide (GO). Of these, wide linear concentration range and low LOD values were observed for ZnMn 2 O 4 /GCE and SmV/ CNF/GCE due to an increased surface area and improved electronic conductivity.…”

Topical treatments rely on drugs that play a crucial role in addressing skin and mucous membrane disorders. Therefore, it is highly needed to utilize accurate analytical techniques that can determine the concentration of these chemicals in various sample matrices, including pharmaceuticals, food, and water. Currently, electrochemical sensors are predominantly used in specific fields such as biomedical, industrial, and environmental monitoring, while they have not yet been incorporated into the pharmaceutical manufacturing industry. However, electrochemical methods employing an expanding range of sensors provide a reliable, cost-effective, and efficient substitute for classical analytical methods. Their potential is highly favorable, offering possibilities for simultaneous determination, miniaturization, and real-time on-site monitoring. This work covers numerous sensors designed between 2020 and 2023 for the determination of topical drugs, highlighting their respective benefits and drawbacks while illuminating emerging trends. Moreover, it discusses the correlation between the used materials and the ease of manufacturing, to the achieved results, including dynamic range, detection limit, sensitivity, and selectivity. This work aims to serve as a valuable resource for researchers, engineers, and policymakers in the evolving field of electrochemical sensing by providing guidance and facilitating decision-making, which could lead to significant innovations in sensor technology.

“…6b shows the correlation coefficient of R 2 = 0.9930 (lower concentrations) and R 2 = 0.9938 (higher concentrations). The diagnostic characteristics of the fabricated device in the linear range of 0.5-89.38 mM and the limit of detection (LOD) determined to be 0.02 mM based on LOD = 3 Â (standard deviation of low concentration)/(slope of the calibration plot) [31][32][33] were analysed. These improved electrochemical properties have such a wide range of applications in identifying different types of environmental contaminants for individual monitoring.…”
