摘要

The multifunctional biocompatible Janus shaped plasmonic-magnetic silver-magnetite nanoparticles have been developed via a single phase microemulsion technique and investigated for different physical properties. The noble metal integration with magnetite nanoparticles introduces superior optical properties into the nanostructures. The dynamic light scattering technique has been used to measure the hydrodynamic size, monodispersity and zeta potential to check their suitability as multimodal agents. The synthesized silver-magnetite nanoparticles are monodispersed and possess colloidal stability. The UV-visible spectra for Janus silver-magnetite nanoparticles shows a surface plasmon resonance peak at 372 and 474 nm which lies in the visible region of electromagnetic spectrum. The photoluminescence spectrum confirms the obtained nanoparticles to be optically active. The measurements of response for bare magnetite as well as silver-magnetite nanoparticles in an alternating magnetic field reveal their suitability in hyperthermia applications. These synthesized integrated magnetite-silver nanostructures show its potential as an excellent candidate for multimodal applications. (C) 2019 The Japan Society of Applied Physics
