Electrochemical characteristics of carvacrol were investigated on a screen-printed electrode (SPE) modified with La2O3/Co3O4 nanocomposite by using voltammetric techniques, which displayed a well-defined peak for sensitive carvacrol determination in phosphate buffer solution (PBS) at pH 7.0. La2O3/Co3O4 nanoparticles demonstrated suitable catalytic activity for carvacrol determination by differential pulse voltammetry (DPV) technique. Besides, determination of carvacrol in a real samples was recognized in the light of electrochemical findings and a validated voltammetric technique for quantitative analysis of carvacrol in a real formulation was proposed. The DPV peak currents were found to be linear in the concentration range of 10.0 to 800.0 μM. The limit of detection (LOD) was found to be 1.0 μM.

A non-enzymatic hydrogen peroxide (H 2 O 2 ) sensor based on a vertically aligned gold nanowire array electrode modified with palladium nanoparticles (PdNP/AuNAE) has been fabricated. PdNP have been deposited onto the AuNAE surface by a hydrothermal reduction method using a borohydride technique. Scanning electron microscope inspection (SEM) has revealed granular Pd particles deposited on the surface of the nanowires. X-ray diffraction (XRD) peak analysis has determined an average crystallite size of 3 to 5 nm for PdNP. The catalytic behavior of PdNP/AuNAE has been studied using amperometry and voltammetry which showed a linear response up to 2 mM of H 2 O 2 with a sensitivity of 530 μA mM −1 cm −2 at 20 • C. This electrode can detect 5 μM (S/N = 3) of H 2 O 2 at normal conditions without using any enzyme or mediator. A high selectivity toward H 2 O 2 (up to 97%) has been obtained using this electrode platform in the presence of common electrochemical interferences such as ascorbic acid, uric acid, acetaminophen and dopamine.
