获得了具有高抗菌（针对革兰氏阳性菌和革兰氏阴性菌）和抗真菌活性的含铜纳米颗粒的低熔点钠钙玻璃粉末。使用含有单分散铜纳米颗粒（d（50）约为30 +/-5nm）的海泡石纤维作为铜纳米颗粒的来源。所观察到的所获得的玻璃粉末的高活性，特别是对酵母的高活性，已经通过考虑从玻璃浸出的Ca 2+对菌落生长的抑制协同效应来解释。
A low melting point soda-lime glass powder containing copper nanoparticles with high antibacterial (against gram-positive and gram- negative bacteria) and antifungal activity has been obtained. Sepiolite fibres containing monodispersed copper nanoparticles (d(50) approximate to 30 +/- 5 nm) were used as the source of the copper nanoparticles. The observed high activity of the obtained glass powder, particularly against yeast, has been explained by considering the inhibitory synergistic effect of the Ca2+ lixiviated from the glass on the growth of the colonies.
