Hello Nano is a nanotechnology brand developed by Nano Institute, focused on creating advanced coatings, materials and products for health protection and other practical applications. Its solutions use components such as natural nanoplatelets, nanotubes, nanosilver, oxides and graphene, formulated into pastes, paints and coatings for integration into finished products. The company describes its Hello Nano coating as providing antibacterial, antiviral, antifungal, anti-mould and anti-allergenic activity, supported by laboratory research. Applications include spray-on treatments for footwear and protective coatings applied by misting or printing to textiles and other surfaces.

Hello Nano also offers protective face masks in 3D and flat designs, made from cotton or synthetic fabric and treated with an active coating. Its wider product and project portfolio includes graphene and carbon-nanotube pastes, natural nanoparticle pastes, luminescent and colour-changing effects, grass paint, and ventilation systems through partner projects. Nano Institute works with businesses to develop and implement nanotechnology-based solutions, presenting its coatings and materials as adaptable to different products and uses.
