We report on a reverse microemulsion method for the synthesis of silver nanocrystals and examine their antibacterial activities. As the molar ratio of water to sodium bis(2-ethylhexyl) sulfosuccinate (AOT) increases to 25, a morphology transition from a sphere-like nanocrystal to a wire-like one was observed. For both the gram-negative and gram-positive bacteria, the wire-like silver nanocrystal showed higher antibacterial activities. We conclude that the morphology of silver nanocrystals dominates their antibacterial activity.
我们报道了一种用于合成银纳米晶体的反向微乳液法，并研究了它们的抗菌活性。随着水与双（2-乙基己基）磺基琥珀酸钠（AOT）的摩尔比增加到25，观察到从球形纳米晶体到线状纳米晶体的形态转变。对于革兰氏阴性菌和革兰氏阳性菌，线状银纳米晶体均表现出更高的抗菌活性。我们得出结论，银纳米晶体的形态主导其抗菌活性。
