These new nanostructures have the nanoring shape, being composed of iron oxides (magnetite or hematite). Such morphology gives the nanoparticles a peculiar magnetic behavior due to their magnetic vortex state. The iron oxide nanorings were obtained using hydrothermal synthesis. X-ray Diffraction confirmed the existence of the desired crystal structure and Scanning Electron Microscopy shows that the magnetite particles had nanometric dimensions with annular morphology (diameter ~250 nm). The nanorings also show intensified magnetic properties and a transition to a vortex state. This study showed that it is possible to obtain magnetic nanorings with properties that can be used in nanotechnological applications (mainly biotechnological ones aimed at the treatment and diagnosis of cancer), in large quantities in a simple synthesis route.</p> Fernando Rodrigues Eduardo Azzolini Volnistem Gustavo Sanguino Dias Ivair Aparecido dos Santos Luiz Cotica Copyright (c) 2022 Fernando Rodrigues, Eduardo Azzolini Volnistem, Gustavo Sanguino Dias, Ivair Aparecido dos Santos, Luiz Cotica 2022-07-17 2022-07-17 5 1 1 7 10.21467/anr.5.1.1-7
