Nucleating acoustic cavitation with optically heated nanoparticles

The utilization of cavitation in high intensity focused ultrasound (HIFU) therapy requires the presence of nucleation sites; nucleation threshold pressures in tissues can exceed 4-5 MPa. We investigate the efficacy of transient vapor cavity generation from laser-illuminated gold nanoparticles as a m...
