From Single-Particle Thermal Asymmetry to Collective Control: Janus Plasmonic Colloids for Photothermal Applications

Cédric Rousseau, Javier González-Colsa, Victor Joris +3

Janus nanoheaters provide a route to break the spatial symmetry of thermoplasmonic heating and generate directionally biased thermal gradients at the nanoscale. However, in realist…
