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) approximately 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 Ca(2+) lixiviated from the glass on the growth of the colonies.
已经获得了一种含有铜纳米粒子的低熔点钠钙玻璃粉末，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。使用含有单分散铜纳米粒子（d(50)约为 30 +/- 5nm）的海泡石纤维作为铜纳米粒子的来源。考虑到从玻璃浸出的 Ca(2+)对菌落生长的抑制协同作用，解释了所获得的玻璃粉末特别针对酵母的高活性。
