Lashkaryov Institute of Semiconductor Physics of National Academy popup.description1 Develop novel hybrid nanoparticles composed of Fe3O4 and Au, Ag, or Au@Ag core-shells and to determine their potential as new functional materials with enhanced magnetic, electronic, and optical properties. popup.description2 The main motivation for research on magneto-plasmonic nanoparticles (NPs) is their potential comprehensive application for therapeutic or curative action, by targeted delivery to body parts and heating by a magnetic field and electromagnetic (photonic) irradiation, as well as for simultaneous monitoring of the result by registering the Raman scattering of tissues or marker molecules enhanced by the plasmonic part of the NPs. The results of fundamental research obtained in the project reveal new aspects of the formation of magnetic properties of Fe3O4 NPs in composite nanosystems and can be further used as a basis for developments of specific therapeutic agents. The developed modified accessible method for the synthesis of Fe3O4 nanoparticles ensures their long-term stability and the possibility of using them as a basis for the synthesis of more complex, composite systems with plasmonic NPs. The revealed effect of a qualitative change in the electron paramagnetic resonance spectrum in Fe3O4 NPs after their modification with Au or Ag nanoparticles requires a more detailed study, in particular, establishing a physical mechanism that directly connects the presence of plasmonic NPs on the surface of magnetic NPs with changes in the properties of the latter. The possibility of a significant enhancement of Raman (inelastic) light scattering (SERS effect) by Fe3O4/Ag composite NPs has been demonstrated, which will allow further optimization of this system for the detection of certain analytes (molecules).
