Our technology acts as a “trojan horse.” Bacteria need iron and generate specialized carrier molecules to gather iron. Our compounds mimics the carriers but deliver copper instead. While copper is ubiquitous and necessary for multiple mammalian systems to function, copper blocks multiple essential processes in the bacteria depending on iron. This dynamic creates a “Catch 22” for the bacteria; to escape the poisoning they have to mutate several independent iron import systems, but in doing so, their biological systems gets disrupted and they can’t survive. However, without mutation of these systems, they become intoxicated by copper and die. This requirement to mutate multiple pathways at once without disrupting the biological pathways, makes it less likely for bacteria to gain resistance against our technology.
