Abstract

This work proposes a sonochemical biosynthesis of magnetoplasmonic nanostructures of FeO decorated with Au and Ag. The magnetoplasmonic systems, such as FeO and FeO-Ag, were characterized structurally and magnetically. The structural characterizations reveal the magnetite structures as the primary phase. Noble metals, such as Au and Ag, are present in the sample, resulting in a structure-decorated type. The magnetic measurements indicate the superparamagnetic behavior of the FeO-Ag and FeO-Au nanostructures. The characterizations were carried out by X-ray diffraction and scanning electron microscopy. Complementarily, antibacterial and antifungal assays were carried out to evaluate the potential properties and future applications in biomedicine.

摘要

这项工作提出了一种通过声化学方法生物合成用金和银修饰的FeO磁等离子体纳米结构。对诸如FeO和FeO-Ag等磁等离子体系统进行了结构和磁性表征。结构表征显示磁铁矿结构为主要相。样品中存在金和银等贵金属，形成了结构修饰型。磁性测量表明FeO-Ag和FeO-Au纳米结构具有超顺磁性行为。通过X射线衍射和扫描电子显微镜进行了表征。作为补充，还进行了抗菌和抗真菌试验，以评估其潜在特性以及在生物医学中的未来应用。
