Lire la suite >Nanoscale photothermoacoustics generation in liquids, by reason of its implications in nanoimaging andtherapeutic, is a booming topic at the forefront of nanoscale heat transfer, optics and biosciences [1]. Withinthis frame, liquid-immersed nanotransducers play a major role as efficient photoacoustic generatorsbecause of their biocompatibility together with tunable optical absorption properties. Research effortsfocused on enhancing photoacoustic conversion acting on the nano transducers’ materials, geometry andsize. Despite these efforts and the applicative interest, the effects of the Kapitza resistance and the laserpulse duration on the acoustic wave generation mechanism [2-4] are yet to be fully uncovered and lack of athorough understanding.Within this context, we review recent developments on the photothermoacoustic of water-immersedgold nanocylinders and nanofilms. The focus is on the acoustic waves launching mechanisms and theircompetition. We demonstrate that the acoustic waves are not only launched by the expansion of water-“thermophone effect”-, but also by the expansion of the nano-object itself- “mechanophone effect”. Both thethermal dynamics and the mechanical response are systematically addressed. The physical parameterscontrolling the thermophone vs mechanophone competition are identified together with their interplay [5].We then extend the investigation to the photoacoustic effect of water-immersed carbon nanotubes,combining microscopic atomistic simulations, analytical models and finite element methods [6]. In this case,in addition to the thermophone vs mechanophone competition, we show how the activation of themechanophone effect can trigger few nanometers wavelengths sound waves in water.Our findings suggest the possibility to exploit liquid-immersed nano-transducers, characterized by a highKapitza resistance, to launch acoustic waves in the liquid while minimizing their temperature increase. Thisstrategy is at variance with what usually suggested in the literature, i.e. minimizing the Kapitza resistance,and is foreseen to play a role in bio-imaging applications at the nano- scale where high frequency acousticwave generation in water is required while avoiding heating effects These findings find generalization alsoin all-solid state systems [7,8].References(1) S.
