Twin or Janus-like gold-iron-oxide plas­monic-superparamagnetic nano­aggregates are made by flame aerosol technology and wrapped up “in-flight” by a transparent silica nanothin film. Its thickness finely tunes the near-infrared absorption of Au nanoparticles allowing for a high light-to-heat efficiency, while iron-oxide facilitates their magnetic placement and in-vivo monitoring by MRI, and killing human breast cancer cells with a short, 4-minute laser irradiation.
