A device, system and method for killing viruses and bacteria in blood. An iontophoretic cartridge destroys blood borne viruses and bacteria using ionized silver nanoparticles. Blood from the arm of the patient is routed to a holding bladder. From the bladder, the blood is pumped to the iontophoretic cartridge. In the cartridge, the blood is split into four tubes containing silver nanowires that treat the blood and destroy the viruses as they flow through the cartridge. The blood is then rerouted to the patients arm.
