She studies a variety of materials produced at the nanometer scale through different methods chemical and physical, changing the paradigms of biosensitivity due to the properties unique to nanomaterials. (RIVAS, 2017; ANZAR, 2020) The development of sensors electrochemicals is one of the largest and fastest growing areas within Analytical chemistry. These devices make use of an electrode as a device signal transducer and are based on charge transfer processes. In an attempt to improve the kinetic and analytical parameters, chemically (EQM), manufactured by modifying the surface of the electrode using various materials. Among them one of the ones that are used very frequently are carbon nanotubes, as they have excellent electrical properties, along with with niclosamide, which has a nitro group, used in redox systems. You nanomaterials have aroused the interest of the scientific community due to their unique physicochemical properties such as high reactivity, quantum effects, size small and large surface. Nanomaterials have dimensions below 100 nm, this group of materials allows access to several new magnetic, electronic, mechanical or optical. (ANZAR, 2020; XIANG, 2020 it was possible to obtain results promising through electrochemical techniques such as cyclic voltammetry and the chronoamperometry, electroanalytical studies were carried out and thus the efficiency of the reaction between immobilized materials and ascorbic acid, determining a catalytic constant of 2.1044 L mol -1s-1.Acesso AbertoNanotecnologiaSensor eletroquímicoConstruçãoNiclosamidaNano tubos de carbonoTrabalho de Conclusão de CursoCNPQ::OUTROS::QUIMICA INDUSTRIAL
