Graphene oxide (GO) and reduced graphene oxide (RGO), due to their large active surface areas, can serve as a platform for biological molecule adhesion (both organic and inorganic). In this work we described methods of preparing composites consisting of GO and RGO and inorganic nanoparticles of specified biological properties: nanoAg, nanoAu, nanoTiO and nanoAgO. The idea of this work was to introduce effective methods of production of these composites that could be used for future biomedical applications such as antibiotics, tissue regeneration, anticancer therapy, or bioimaging. In order to characterize the pristine graphene materials and resulting composites, we used spectroscopic techniques: XPS and Raman, microscopic techniques: SEM with and AFM, followed by X-Ray diffraction. We obtained volumetric composites of flake graphene and Ag, Au, AgO, and TiO nanoparticles; moreover, Ag nanoparticles were obtained using three different approaches.
氧化石墨烯（GO）和还原氧化石墨烯（RGO）由于其较大的活性表面积，可作为生物分子（包括有机和无机分子）附着的平台。在这项工作中，我们描述了制备由GO、RGO与具有特定生物学特性的无机纳米颗粒（纳米银、纳米金、纳米二氧化钛和纳米氧化银）组成的复合材料的方法。这项工作的思路是引入这些复合材料的有效生产方法，可用于未来的生物医学应用，如抗生素、组织再生、抗癌治疗或生物成像。为了表征原始石墨烯材料和所得复合材料，我们使用了光谱技术：X射线光电子能谱（XPS）和拉曼光谱，显微技术：扫描电子显微镜（SEM）和原子力显微镜（AFM），随后进行X射线衍射分析。我们获得了片状石墨烯与银、金、氧化银和二氧化钛纳米颗粒的体积复合材料；此外，使用三种不同方法获得了银纳米颗粒。
