Janus and core@shell gold nanorod@Cu2-xS supraparticles: reactive site regulation fabrication, optical/catalytic synergetic effects and enhanced photothermal efficiency/photostability.

We herein present a reactive site regulation strategy for fabricating well-defined Janus and core@shell gold nanorod-Cu2-xS dual metal-semiconductor plasmonic supraparticles. In addition to enhanced photothermal efficiency and photostability, the nanohybrids possess synergetic photo-thermal and chemical dynamic therapy and corresponding application potential.
