“…In addition, some other solutions can lead to increase in the sensitivity of CNTs, where SWCNTs or MWCNTs, during their interaction with the gases. The chemical process such as functionalization which sometimes can show effects even at room temperature (Tavakkoli, Akhond, Ghorbankhani, & Absalan, 2020). The process of functionalization is the addition of metals, organic active groups; such as carboxylic and hydroxyl group, ionic liquids and many others to achieve the properties which are required.…”

Nanostructured materials are of extraordinary intrigued within the vitality capacity and change field due to their great mechanical and electrical properties. Carbon nanotubes are substances which have been shown those properties. They are an interesting nanostructure that has promising possibilities for future applications. CNTs have different allotropes such as fullerenes, CNTs and graphene. They have been subjects of wide investigate intrigued due to their potential for novel applications spread over the logical range. Graphene to a great extent considered the essential of all carbon allotropes can be formed to make 0D fullerene or rolled to create 1D CNTs. CNTs come in numerous shapes which shift by diameter and by the course of action of their hexagonal clusters within the grid. These contrasts result in the changes to the thickness of electronic states and give each sort of CNTs one of a kind of electrical and basic properties. Progresses in synthesis and decontamination have given analysts get to higher quality materials which has empowered distant better and improved understanding of their properties and their guarantee for future electronic applications.

“…In high concentrations it can cause serious harm to human health and the environment, despite the fact that, in living organisms, H 2 O 2 is a by-product of metabolism for a wide range of biological and chemical processes, occurring under the influence of external stimuli and intracellular processes [ 1 – 2 ]. Disruption of the natural regulation process and increasing concentration of H 2 O 2 in the blood can cause severe diseases such as Alzheimer's and Parkinson's [ 3 ], premature aging of cells [ 4 ], death of nerve cells [ 3 , 5 – 6 ], loss of brain mass [ 7 ], and cancer [ 8 – 11 ]. For this reason, targeted monitoring of the concentration of H 2 O 2 in body fluids can be used in the diagnosis of these diseases [ 12 – 15 ].…”

“…Nanostructured materials are widely used as the working surface of the electrode [ 47 – 49 ]. The most common are transition metal nanoparticles [ 33 , 37 , 50 – 54 ], carbon nanotubes [ 8 ], metal oxides [ 55 – 64 ], graphene [ 32 – 33 ], and ordered mesoporous carbon [ 38 , 65 – 66 ]. Compared to bulk materials, nanostructures have higher catalytic activity and a significantly increased surface area-to-volume ratio, which makes it possible to significantly increase both sensitivity of the sensor and rate of detection of H 2 O 2 .…”

This article describes the synthesis of nanostructured copper oxide on copper wires and its application for the detection of hydrogen peroxide. Copper oxide petal nanostructures were obtained by a one-step hydrothermal oxidation method. The resulting coating is uniform and dense and shows good adhesion to the wire surface. Structure, surface, and composition of the obtained samples were studied using field-emission scanning electron microscopy along with energy-dispersive spectroscopy and X-ray diffractometry. The resulting nanostructured samples were used for electrochemical determination of the H2O2 content in a 0.1 M NaOH buffer solution using cyclic voltammetry, differential pulse voltammetry, and i–t measurements. A good linear relationship between the peak current and the concentration of H2O2 in the range from 10 to 1800 μM was obtained. The sensitivity of the obtained CuO electrode is 439.19 μA·mM−1. The calculated limit of detection is 1.34 μM, assuming a signal-to-noise ratio of 3. The investigation of the system for sensitivity to interference showed that the most common interfering substances, that is, ascorbic acid, uric acid, dopamine, NaCl, glucose, and acetaminophen, do not affect the electrochemical response. The real milk sample test showed a high recovery rate (more than 95%). According to the obtained results, this sensor is suitable for practical use for the qualitative detection of H2O2 in real samples, as well as for the quantitative determination of its concentration.
