Abstract

A tunable pulsed laser with nano-second pulse duration is used to generate microbubbles in highly diluted nanoparticle (Au, TiO₂ and ZnO) suspensions. The microbubble explosion may produce shock wave which is in-phase detected by a low-frequency piezoelectric transducer. The effects of particle size and category on the threshold laser fluence of shock wave generation and the wave intensity are investigated. The interaction between laser and nanoparticles has significant application in biomedicine such as photothermal diagnostic and therapy, as well as cosmetic or drug delivery in skin.
