TiO-Ag-NP adhesive photocatalytic films able to disinfect living indoor spaces with a straightforward approach.

TiO-Ag doped nanoparticulate (TiO-Ag-NP) adhesive photocatalytic films were used to assess the ability in dropping down the burden of indoor microbial particles. The application of an easy-to use photocatalytic adhesive film to cleanse indoor living spaces from microbial pollution, represents a novelty in the field of photocatalytic devices. Reduction was attained by photocatalysis in selected spaces, usually with overcrowding (≥ 3 individuals) in the common working daily hours, and upon indoor microclimate monitoring.
