Nanoparticles as antifungal additives for indoor water borne paints

There are nanotechnology-based materials that can be used as antimicrobial additives in different appli-cations such as water-borne paints. Antimicrobial paints are important tool in order to avoid indoorbiological colonization and therefore prevent paint bio-deterioration and health problems in peo...
