Rapid synthesis and characterization of silver-loaded graphene oxide nanomaterials and their antibacterial applications

All original data used in figures and tables of the manuscript are available in the dataset, which includes the X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, scanning electron microscopy with energy dispersion spectroscopy, zeta potential analysis and antibacterial properties measurement. Ultrasound was practically used in large-scale production of water-soluble silver/graphene oxide (Ag/GO) by reducing the silver ions (Ag+) attached to graphene oxide into silver nanoparticles. The infrared and X-ray photoelectron spectra indicated that there is a strong interaction between Ag and GO. The morphology analysis showed that AgNPs having a monodisperse size was well dispersed on the surface of the GO nanosheet. The zeta potential analysis showed that the Ag/GO nanomaterials suspension has high stability. In addition, the Ag/GO nanomaterials exhibited an effective antibacterial activity against Escherichia coli ...

本手稿所有图表所使用的原始数据均收录于本数据集，涵盖X射线衍射（X-ray diffraction）、傅里叶变换红外光谱（Fourier transform infrared spectroscopy）、X射线光电子能谱（X-ray photoelectron spectroscopy）、透射电子显微镜（transmission electron microscopy）、配备能量色散光谱的扫描电子显微镜（scanning electron microscopy with energy dispersion spectroscopy）、Zeta电位分析（zeta potential analysis）以及抗菌性能测试等相关数据。超声技术被实际应用于水溶性银/氧化石墨烯（Ag/GO）的规模化制备过程，具体通过将吸附于氧化石墨烯表面的银离子（Ag+）还原为银纳米颗粒（AgNPs）来实现。傅里叶变换红外光谱与X射线光电子能谱的表征结果表明，银与氧化石墨烯之间存在较强的相互作用。形貌分析结果显示，尺寸单分散的AgNPs均匀分散于氧化石墨烯纳米片的表面。Zeta电位分析结果表明，该Ag/GO纳米材料悬浮液具有较高的分散稳定性。此外，该Ag/GO纳米材料对大肠杆菌（Escherichia coli）展现出有效的抗菌活性……
