Femtosecond laser generation of bimetallic oxide nanoparticles with potential X-ray absorbing and magnetic functionalities for medical imaging applications

Bimetallic nanoparticles have gained vivid attention due to their unique and synergistic properties. They can be used in fields such as solar cells, optics, sensing, well medicine. The generation of bimetallic nanoparticles, containing oxide phases both magnetic X-ray attenuating metals for bioimaging applications has been challenging with traditional chemical synthesis methods. An alternative is the from binary ceramics by laser ablation liquid. However, applicability this technique production hybrid consisting absorbing elements not demonstrated yet. In work, novel composed iron-tantalum, iron-tungsten, iron-bismuth were produced a reaction-sintering method. bulk samples characterized scanning electron microscopy, energy dispersive spectroscopy, diffractometry. Nanoparticles aqueous ethanol solutions employing femtosecond transmission selected area diffraction, spectroscopy. results that subsequent liquids leads successful without core-shell morphology. addition, it was found threshold fluence crystallinity synthesized governed nature metallic employed pave way single step well-defined could potentially exhibit absorption properties suitable multimodal imaging applications.
