  • 摘要: 以柠檬酸钠为还原剂通过简单的超声加热处理,原位制备出氧化石墨烯纳米银复合材料.采用X射线光电子能谱、紫外可见吸收光谱、透射电子显微镜等手段对氧化石墨稀纳米银复合材料进行表征.结果表明纳米银呈球状均匀分布在氧化石墨烯表面.以大肠杆菌(MG1655)为模型菌,通过细菌生长动力学试验及荧光染色试验评价了氧化石墨烯纳米银复合材料的抑菌性能.结果表明,氧化石墨烯复合材料对大肠杆菌有较强的抑菌效果,且其卓越的抑菌效果是通过氧化石墨烯纳米银材料的协同作用来完成的.因此,氧化石墨烯纳米银是一种非常有效的抑菌材料.
    Abstract: Graphene oxide-silver nanoparticles (GO-AgNPs) was prepared through simple ultrasound heating process with sodium citrate as reducing agent. The GO-AgNPs were characterized by X-ray photoelectron spectroscopy, UV-vis spectra and transmission electron microscope. The antibacterial activity of the GO-AgNPs against the microorganism Escherichia coli was investigated using the dynamics of growth curve and fluorescence experiment. The as-prepared composites exhibited strong antibacterial activity, and the excellent antibacterial effect of GO-AgNPs was due to a synergistic effect of GO and AgNPs. These promising results show that it is an outstanding antibacterial material.
