A new discovery by Arizona State University (ASU) scientists shows that two specific metallic elements in the right kinds of clay can kill disease-causing bacteria that infect humans and animals. Says Enriqueta Barrera, a program director in the National Science Foundation (NSF) Division of Earth Sciences, which funded the research:

Scientists have found that certain clays possess germ-killing abilities, but how these work has remained unclear.

Says Enriqueta Barrera, a program director in the National Science Foundation (NSF) Division of Earth Sciences, which funded the research:

“The novelty of this research is two-fold: identifying the natural environment of the formation of clays toxic to bacteria, and how the chemistry of these clays attacks and destroys the bacteria. This geochemical mechanism can be used to develop products that act on bacteria resistant to antibiotic treatment.”

Antibacterial Trojan Horse

Says Lynda Williams, a clay-mineral scientist at ASU:
