In this study, we describe a novel strategy for the synthesis and characterization of single-carbon nanotube nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The fabrication process involves a two-step approach, first attaching SWCNTs onto a compatible substrate and then introducing Fe3O4 nanoparticles via a solvot
