Abstract

In this paper we propose a mathematical model and an approximate equation to explain the behavior found on the photoacoustic effect generated by laser-induced nanobubbles in colloidal gold solutions. To obtain the equation, we developed a simulation program based on the widely known Rayleigh-Plesset model. A set of measurements was carried out to assess its accuracy on real samples. The equation gives a good approximation for spherical gold nanoparticles with sizes between 10 and 80 nm, and laser fluences larger than the fluence threshold for bubble formation.
