This research investigates the enhancement of barley's resistance to salt stress by integrating nanoparticles and employing a nanostructured CoO sensor for the electrochemical detection of hydrogen peroxide (HO), a crucial indicator of oxidative stress. The novel sensor, featuring petal-shaped CoO nanostructures, exhibits remarkable precision and sensitivity to HO in buffer solution, showcasing notable efficacy in complex analytes like plant juice. The research establishes that the introduction of FeO nanoparticles significantly improves barley's ability to withstand salt stress, leading to a reduction in detected HO concentrations, alongside positive impacts on morphological parameters and photosynthesis rates.

ZnO nanostructures are promising candidates for use in sensors, especially in electrochemical sensors and biosensors, due to their unique physical and chemical properties, as well as sensitivity and selectivity to several types of contamination, including heavy metal ions. In this work, using the hydrothermal method, nanostructures of ZnO were synthesized in four different morphologies: nanorods, nanoneedles, nanotubes and nanoplates. To determine the peculiarities of adsorption for each morphology, a series of electrochemical measurements were carried out using these nanostructured ZnO coatings on the working electrodes, using aqueous solutions of Pb(NO) and Cd(NO) as analytes with different concentrations.
