Abstract: Method for obtaining a material containing nanostructured reactive molecules based on niobium compounds, the products obtained, and the use thereof as a chemical/biological barrier on surfaces. The nanostructured hybrid material can be used as a component in cosmetic products, intensifying the efficiency and action time thereof. Furthermore, the material can be incorporated into different surfaces, including fabric, retaining its anti-bacterial and anti-viral properties. The material can also be applied in the form of a gel or liquid spray. The niobium nanoparticles combined with quaternary ammonium compounds for sprays and with methylene blue colour to form sanitizing gels are highly efficient in deactivating coronavirus, with prolonged stability and activity.

Abstract: Nanostructured materials based on niobium oligomers, organic cations, quaternary ammonium salts and copper cations (Cu2+) with high foliar antifungal activity, which can also be used as biomarkers.

Abstract: A teeth whitening based on the generation of active oxygen in the form of oxygen radical species in situ and method for producing the whitening gel which has modified niobium compounds and its activity maximized if applied with hydrogen peroxide in low concentrations, with stabilization by a thickener. The whitening gel can be used without light treatment and with greater efficiency than commercial products and with a significant potential to reduce side effects. The whitening toothpaste and gels including modified niobium compounds associated with cations, the mechanisms of whitening action comes from electronic excitation, from the incidence of radiation on niobium compounds with cations, due to the action of the functional chemical groups present in the nanoparticles, even in the absence of light. In addition, the compounds can act as chemical whiteners, leading to a decrease in caries bacteria due to the oxidant functional groups in the nanoparticles.
