MVX One of these self-disinfecting products is MVX. MVX contains titanium dioxide which by the use of nanotechnology is now available for use in the health sector. Working as a photocatalyticum it generates, in the presence of light, hydroxy radicals and oxygen radicals for at least five years after coating hospital surfaces (durability test TUV Rheinland). Laboratory tests show that MVX is effective in killing bacteria, viruses and fungi (see attachment 1 for summary test results).
