Anti-fingerprint photocatalytic nanostructure for transparent surfaces

A structure comprising:

• a transparent substrate;
• and
• a multi-layer optically transmissive nanoparticle structure residing on the substrate comprising an outermost layer of titanium dioxide nanoparticles wherein the outermost layer of titanium dioxide nanoparticles of the multi-layer structure is superhydrophilic and oleophilic, and alternating layers of low and high index of refraction materials below the outermost layer to provide broadband anti-reflectivity
• wherein the alternating layers of low and high index of refraction materials form a nanoporous coating and have a smaller refractive index than the substrate and
• the optically transmissive nanoparticle structure capable of wicking sebum into the nanoporous coating of the nanoparticle structure followed by photocatalytic degradation.
