Abstract

Nanoscale photothermoacoustics generation in liquids, by reason of its implications in nanoimaging and therapeutic, is a booming topic at the forefront of nanoscale heat transfer, optics and biosciences [1]. Within this frame, liquid-immersed nanotransducers play a major role as efficient photoacoustic generators because of their biocompatibility together with tunable optical absorption properties. Research efforts focused on enhancing photoacoustic conversion acting on the nano transducers’ materials, geometry and size. Despite these efforts and the applicative interest, the effects of the Kapitza resistance and the laser pulse duration on the acoustic wave generation mechanism [2-4] are yet to be fully uncovered and lack of a thorough understanding.
