But how does the oligodynamic effect work? While the mechanism is not yet fully understood by modern science, studies suggest that copper ions cause membrane damage to bacteria by affecting the protein in the bacteria's cell walls thereby resulting in their precipitation and inactivation.

How does oligodynamic effect kill bacteria and viruses in general?

Termed the “Oligodynamic Effect”, the process actually isn't well understood, but it's thought that, in simple terms, the metal ions bind with proteins in bacteria cells, a fatal attraction which renders the bacteria inactive.

What is the mechanism of oligodynamic action?

In oligodynamic action, metal ions concentrate on the surface of the living object (bacteria, algae, and so on), which causes blocking of the free carbonyl and sulfhydryl groups of the surface structures. Oligodynamic action extends to enzyme systems and even to the activity of inorganic catalysts.
