No dioding subsequently occurs with this process. Some evidence suggests that immune cells like macrophages — which gobble up and destroy bacteria, viruses and other microbes — may be capable of engulfing and sequestering germs in an acidic “ball of death” chamber that’s then spiked with lethal doses of copper, Dr. Johnson said.
