Risks associated with copper and copper oxide nanoparticles

Copper and copper oxide nanoparticles are used for their antibacterial and antifungal properties.

What about environmental and health risks?

Data are still very patchy, but caution is necessary due to their possible accumulation in certain organs – notably the liver and spleen – as well as potential mutagenic/genotoxic and immunotoxic/nephrotoxic effects1See Opinion on Copper (nano) and Colloidal Copper (nano), Scientific Committee on Consumer Safety (SCCS), March 2021.
