The filtering and sterilization process of the water purification device. On the left is an example of microorganisms that commonly contaminate drinking water. The pathogens are trapped at the surface of the nanowire-carbon nanotube composite-based filter. On the right is an illustration of how UV light generates reactive oxygen species on the surface of the filter UV illumination.
