Nanoparticles of tungsten oxide and ultraviolet light are wounding power to kill fungus and bacteria
Tungsten (wolfram) oxide WO3 is a contrast in X-rays substance which is very perspective for computer tomography. The studies on the extent of its safety for humans has shown that under ultraviolet irradiation, tungsten oxide becomes deleterious for bacteria and fungus.
The scientists note that the newly obtained data allow for creating antibacterial coverings for hospitals, public transport, and other public places. Under the quartz treatment of surfaces covered with tungsten oxide, the sterilization effect of ultraviolet of quartz lamps will be boosted, and almost all prokaryote cells will be killed. Outside hospitals, the similar effect can be achieved by solar light. By combining tungsten oxide with ultraviolet lamps of high capacity, one could apply nanoparticles of this compound also for purification of wastewaters.
