This work proposes a sonochemical biosynthesis of magnetoplasmonic nanostructures of Fe 3 O 4 decorated with Au and Ag. The magnetoplasmonic systems, such as Fe 3 O 4 and Fe 3 O 4 -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 Fe 3 O 4 -Ag and Fe 3 O 4 -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. |
