Abstract
A low melting point soda-lime glass powder containing copper nanoparticles with highantibacterial (against gram-positive and gram-negative bacteria) and antifungal activityhas been obtained. Sepiolite fibres containing monodispersed copper nanoparticles (d50≈30 ± 5 nm) were used as the source of the copper nanoparticles. The observedhigh activity of the obtained glass powder, particularly against yeast,has been explained by considering the inhibitory synergistic effect of theCa2+ lixiviated from the glass on the growth of the colonies.
