Fabrication and experimental study of microfluidic device for particle separation using standing surface acoustic waves (SSAW)

In recent years, much research effort in the field of microfluidics has been directed at studying the behaviour of suspended particles when acted upon by surface acoustic waves (SAW). In particular, the use of standing surface acoustic waves (SSAW) has shown great potential in manipulating objects o...
