Gold nanoparticles enhance laser heating

Abstract:
Researchers at Ohio University, US, have used a laser to heat gold nanoparticles embedded in ice. The nanoparticles enabled the laser to melt the ice at lower light intensities. "The motivation is using gold nanoparticles as site-directed nano heaters that can be actuated with optical light," Hugh Richardson of Ohio University told nanotechweb.org. "The applications are broadly based photothermal therapy, lithography, chemical reaction initiation at specific sites and the impact is large."
