BasicShield + is based on TiO2 along with Silver nanoparticles, it is a photocatalytically active product for the coating of surfaces. The coating is able to decompose organic compounds on a molecular level, but also viruses, germs and bacteria just by means of light and makes surfaces hydrophilic and antibacterial.
The addition of noble metal (such as silver) to titanium dioxide enhances its photocatalytic efficiency. The doping process deposits Ag nanoparticles on the surface of TiO2 nanoparticles.
Silver ions (Ag+) are known to cause denaturation of proteins present in bacterial cell walls and slow down bacterial growth.
