Role of the interfacial thermal conductance on the thermoplasmonic response of Janus nanoparticles under nanosecond pulsed illumination

Abstract: Janus nanoparticles, incorporating plasmonic materials, have become important in thermoplasmonics. Controlled by pulsed excitation lasers, these nanostructures transfer thermal energy through material-fluid interfaces, regulated by interfacial thermal conductance. Here, we will present our most recent results in revealing the influence of interfacial thermal conductance on the thermal relaxation of metal-polymer Janus nanoparticles that exhibit directional heat dissipation under pulsed illumination. In particular, we will discuss how neglecting the temperature dependence of thermophysical properties leads to an overestimation of the nanoparticle's temperature. We demonstrate the potential of gold/polymer semishell nanostructures as effective nanoheaters for photothermal therapies. Our findings can motivate the exploration of innovative strategies for efficient nanoheating platforms in temperature-controlled devices.
