Microfabricated acoustic cavity for the manipulation of suspended particles

The aim of the current work is to develop a new, high frequency (12 MHz) system where microfabrication techniques are employed to construct a high Q, resonant chamber with resulting high values for the standing wave acoustic pressure amplitude. The long-term goal is to develop a microfabricated acoustic cavity for the manipulation of nanoparticles (in suspension) which is gravity and orientation free in functionality and independent of particulate concentration. This will provide a generic technology for a diversity of fields of application
