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.
