Abstract

In this study, we compared the final core–shell products produced in the presence or absence of ultrasonic waves and evaluated the antibacterial properties of the core–shell. When ultrasonic wave was used, a complete core–shell structure with a silica shell coated on an individual core particle could be observed. Transmission electron microscopy and energy dispersive X-ray spectroscopy were performed to confirm the shape of the core–shell structure formed in each case. In order to evaluate the antibacterial activity of the core–shell with the Cu core, their antibacterial activity was evaluated by the KS J 4206 and JIS Z 2801. The Cu–SiO₂ core–shell showed a high level of microbial reduction and it also worked as filler in the glass powder.

超声波合成Cu-SiO 2核壳及其抗菌活性

摘要

在这项研究中，我们比较了在有或没有超声波的情况下生产的最终核壳产品，并评估了核壳的抗菌性能。当使用超声波时，可以观察到完整的核-壳结构，并在单个核颗粒上涂覆了二氧化硅壳。进行了透射电子显微镜和能量色散X射线光谱分析，以确认每种情况下形成的核-壳结构的形状。为了评价核-壳与铜芯的抗菌活性，其抗菌活性通过KSĴ4206和JIS Z 2801进行评价所述Cu-的SiO ₂的核-壳表明微生物还原的高电平，并且它也用作玻璃粉中的填料。
