The antibacterial and antifungal activity of a low melting point soda-lime glass powder containing silver nanoparticles has been studied. Nano-Ag sepiolite fibres containing monodispersed silver nanoparticles (d(50) approximately 11 +/- 9 nm) were used as the source of silver. This powder presents a high antibacterial (against gram-positive and gram-negative bacteria) as well as antifungal (against I. orientalis) activity. The observed high activity against yeast has been explained by considering the inhibitory effect of the Ca(2+) lixiviated from the glass on the growth of the yeast colonies.
对含有银纳米颗粒的低熔点钠钙玻璃粉末的抗菌和抗真菌活性进行了研究。含有单分散银纳米颗粒（d(50)约为11±9纳米）的纳米银海泡石纤维被用作银源。这种粉末具有很高的抗菌（针对革兰氏阳性菌和革兰氏阴性菌）以及抗真菌（针对东方伊萨酵母）活性。通过考虑从玻璃中浸出的Ca(2+)对酵母菌落生长的抑制作用，解释了观察到的对酵母的高活性。
