A nanoparticle spray can turn regular paper into superpaper, rendering it waterproof, antimicrobial, magnetic and probably very expensive. Who said paper was an old technology?

Scientists at the Istituto Italiano di Tecnologia in Genoa, Italy, developed a process to cover any cellulose fiber, like paper or fabric, with a reactive coating. It involves combining the fiber molecules with a nanoparticle solution, creating a polymer matrix.
