The possibility of micro-manipulation of small particles by surface acoustic streaming is proposed. At a capillary waves formation on the liquid surface, ultrasonic fountain is generated. We propose that at the time when ultrasonic atomization occurs, surface acoustic streaming, which locates on the very thin layer of liquid surface is generated. Surface acoustic streaming conveys small particles on the liquid surface, and gathers small particles to construct the rich layer of small particles.
