Herein, a facile procedure was developed for designing an electrochemical sensor based on pencil graphite electrode modified with electrochemically synthesized silver and copper nanoparticles (AgNP and CuNP) supported on functionalized multiwalled carbon nanotubes (fMWCNTs). The electrochemical and morphological characterization was carried out by cyclic voltammetry, Electrochemical Impedance Spectroscopy, Powder X‐ray diffraction, Field Emission Scanning Electron Microscopy, Transmission electron microscopy and Atomic Force Microscopy. The designed sensor exhibited electrocatalytic behavior towards the reduction of Imazethapyr. Results indicates the combination of AgNPs, CuNPs and fMWCNTs on PGE produced remarkable enhancement in electrocatalytic and sensing properties. Various electro‐kinetic parameters like Rct, kapp, n, α, E0, k0, Γ, D and k have been evaluated by CV, impedance and Chronoamperometric studies. The electrochemical performance was improved by optimizing the effect of pH, scan rate, amount of fMWCNTs and deposition parameters of AgNP and CuNP. The sensor was efficaciously applied for determination of Imazethapyr and exhibited a linear correlation in the concentration range of 0.01–5.0 μg mL−1 with low detection limits, 0.159 ng mL−1 using AdSWV. The fabricated sensor exhibited good accuracy, acceptable stability and high efficacy for quantitative determination of Imazethapyr in real samples with notable recoveries ranging from 98 % to 100.2 %.

Triptycenes (TT) scaffolds have emerged as attractive organic ligands for the synthesis of MOF electrocatalytic materials because their characteristic rigid trigonal topology interferes with close molecular packing, thus favoring the formation of open structures with significant volume available for the inclusion of guests. In this work, a novel conductive metal-organic framework based on 2,3,6,7,14,15-hexahydroxytriptycene (Cu-HHTT) is synthesized in situ by a simple hydrothermal method. As an bifunctional electrocatalyst for efficient glucose electrooxidation and H2O2 electroreduction in alkaline and neutral electrolytes, the non-enzymatic electrochemical sensor has a sensitivity of 47200 mA μM-1 cm-2 and 5170 mA μM-1 cm-2 to glucose and H2O2 with detection limits of 0.16 μM and 0.54 μM (S/N = 3), respectively, and successfully used in the detection of actual serum, orange juice and milk samples.The method provides a new idea for the preparation and application of MOF materials based on triptycene scaffolds.

“…The combination of PB with CNTs and nanostructured metal oxides ( Roushani et al, 2013a ; Roushani et al, 2013b ; Salimi et al, 2013 ; Roushani and Karami, 2014 ; Roushani and Dizajdizi, 2015 ; Roushani and Dizajdizi, 2016 ) can generate novel results for good electrical communication between the recognition system and the electrode surface. Zirconium oxide (ZrO 2 ) nanoparticles have been used as an electrochemical biosensor platform for oral cancer detection by cyclic voltammetry ( Zong et al, 2007 ; Zhao et al, 2020 ; Rathee et al, 2021 ).…”

In this investigation, a hydrogen peroxide (H2O2) electrochemical sensor was evaluated. Prussian blue (PB) was electrodeposited at a glassy carbon (GC) electrode modified with titanium dioxide– and zirconia-doped functionalized carbon nanotubes (TiO2.ZrO2-fCNTs), obtaining the PB/TiO2.ZrO2-fCNTs/GC-modified electrode. The morphology and structure of the nanostructured material TiO2.ZrO2-fCNTs was characterized by transmission electron microscopy, the specific surface area was determined via Brunauer–Emmett–Teller, X-ray diffraction, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The electrochemical properties were studied by cyclic voltammetry and chronoamperometry. Titania-zirconia nanoparticles (5.0 ± 2.0 nm) with an amorphous structure were directly synthesized on the fCNT walls, aged during periods of 20 days, obtaining a well-dispersed distribution with a high surface area. The results indicated that the TiO2.ZrO2-fCNT–nanostructured material exhibits good electrochemical properties and could be tunable by enhancing the modification conditions and method of synthesis. Covering of the nanotubes with TiO2-ZrO2 nanoparticles is one of the main factors that affected immobilization and sensitivity of the electrochemical biosensor. The electrode modified with TiO2-ZrO2 nanoparticles with the 20-day aging time was superior regarding its reversibility, electric communication, and high sensitivity and improves the immobilization of the PB at the electrode. The fabricated sensor was used in the detection of H2O2 in whey milk samples, presenting a linear relationship from 100 to 1,000 μmol L−1 between H2O2 concentration and the peak current, with a quantification limit (LQ) of 59.78 μmol L−1 and a detection limit (LD) of 17.93 μmol L−1.
