摘要

利用纳米颗粒（NP）作为传统方法的替代品来保护表面免受细菌感染正变得越来越流行。纳米技术已显示出提供持久保护的前景。本研究的重点是通过在不同温度下的热氧化在铜表面合成Cu/CuxO复合材料。测量了复合材料的光学反射光谱，并在526-600nm范围内观察到等离子体边缘。为了测试复合材料的抗菌性能，对金黄色葡萄球菌进行了抑菌区试验。结果表明，在100°C下处理的样品中发现了最大的抑制区。此外，还发现热氧化降低了铜纳米颗粒对细菌的抑制能力。

The Antimicrobial Activity of Cu/CuxO Composites Synthesized by Thermal Oxidation of Copper Tablets

The utilization of nanoparticles (NPs) as an alternative to conventional methods to protect surfaces from bacteria is becoming increasingly popular. Nanotechnology has shown promise in providing long-lasting protection. This study focused on synthesizing Cu/CuxO composites on copper surfaces through thermal oxidation at varying temperatures. Optical reflectivity spectra of the composites were measured, and the plasma edges were observed in the range of 526-600 nm. To test the antibacterial properties of the composites, inhibition zone tests were conducted for Staphylococcus aureus. Results showed that the largest zone of inhibition was found in the sample treated at 100ο C. Furthermore, it was discovered that thermal oxidation decreased the ability of copper nanoparticles to inhibit bacteria.
