“…The potentiometric experiment showed a low limit of detection (LOD), which can be calculated when the detecting emf values of the sensors drop by 17.9 mV. [46] The standard TRF-TPB sensor had a detection level of 1.3×10 À 7 mol/L, while the functionalized TRF-TPB-CaO/ZnO-NCS sensor had a level of 2.5×10 À 10 mol/L. The accuracy of the analytical technique is one of the most important parameters that should be evaluated and ensured.…”

The unique properties of calcium oxide (CaO) and zinc oxide (ZnO) at the nanoscale have attracted the interest of scientists as promising electrically conductive substances for sensing purposes. The content of terbinafine hydrochloride (TRF) in pharmaceutical tablets was determined using a novel coated, wire‐functionalized CaO/ZnO nanocomposite membrane sensor biogenically produced from Lavandula spica extract. Sodium tetraphenylborate was used to prepare the active material (TRF‐TBP). The newly modified sensor gave excellent potentiometric sensitivity with the least squares regression equation EmV=(−58.88X±0.3)+log [TRF]+549.78 and covered a wide linear range (5.0×10−9–1.0×10−2 mol/L) of TRF samples. In contrast, the standard TRF‐TBP sensor wasn't as sensitive when (2.5×10−6–1.0×10−2 mol/L). TRF solutions with regression equation of (−55.728X±0.7)+log [TRF]+396.64. The appropriate pH range was 3–6. The principles of analytical methodology were applied to investigate the validity and suitability of the proposed technique. The proposed sensors were found to be suitable and efficient for the detection of TRF on tablets.

“…Te active sites, electrochemically active surface area, surface energy, and other factors are generally closely related to the electrocatalytic properties of metal oxide nanoparticles [34]. Te catalytic materials were fabricated as small as possible to increase the number of available active sites and the available surface area so that the metal oxide-based nanoparticles exhibit high sensing performance [35][36][37][38].…”

The advanced and highly functional properties of Al2O3 and NiO nanoparticles promote the widespread use of metal oxides as remarkable electroactive materials for sensing and electrochemical applications. The proposed study describes a comparison of the sensitivity and selectivity of two modified wire membrane sensors enriched with Al2O3 and NiO nanoparticles with conventional wire membranes for the quantification of the antidiabetic drug metformin hydrochloride (MTF). The results show linear relationships of the enriched Al2O3 and NiO nanosensors over the concentration ranges 1.0 × 10−10–1.0 × 10−2 mol L−1 and 1.0 × 10−6–1.0 × 10−2 M for both the modified sensors and the conventional coated wire membrane sensors. The regression equations were EmV = (52.1 ± 0.5) log (MTF) + 729 for enriched nanometallic oxides, EmV = (57.04 ± 0.4) log (MTF) + 890.66, and EmV = (58.27 ± 0.7) log (MTF) + 843.27 with correlation coefficients of 0.9991, 0.9997, and 0.9998 for the aforementioned sensors, respectively. The proposed method was fully validated with respect to the recommendations of the International Union of Pure and Applied Chemistry (IUPAC). The newly functionalized sensors have been successfully used for the determination of MTF in its commercial products.
