Abstract

This study continues the series of experiments revealing high antibacterial properties of monovalent copper ions (Cu+). While previous studies showing that monovalent copper ions (Cu+) are a robust antibacterial substance were conducted in an anaerobic atmosphere with acetonitrile as a ligand stabilizing monovalent copper ions [1,2], this study focuses on preparations that generated an effective antibacterial concentration of monovalent copper ions at room conditions. We found that in a semi-hydrophobic environment, divalent copper with ascorbic acid (or a derivative of ascorbic acid) produces and maintains a stable concentration of monovalent copper ions [3].
