Copper monodispersed nanoparticles (2–5 nm) embedded into submicron particles of sepiolite (Mg8Si12O30(OH)4(H2O)4·8H2O), suitable to be used for biological applications have been obtained after a specific treatment and subsequent reduction process. Cu/Sepiolite particles have revealed as a strong bactericide (similar to Triclosan) so that they were able to decrease the starting microorganism concentrations of Staphylococcus aureus or Escherichia coli by 99.9%.
