Thermoplasmonics In article number 2000198, Luciano De Sio and co-workers demonstrate the extraordinary versatility of gold nanoparticles as nano-sources of heating. From tunable optical components to advanced medical applications, thermoplasmonics represents a far-sighted and multidisciplinary research field to realize innovative, light-driven applications. What's more, thermoplasmonics can boost the fight against COVID-19 thanks to the realization of light disinfected face masks.
