ABSTRACT:
A method of non-contact micromanipulation using ultrasound includes providing a concave ultrasound transducer in a liquid medium in which micro particles are distributed, positioning a reflector at the focal point position of the transducer and radiating ultrasound from the transducer to form a standing wave field between the transducer and the reflector to align and trap micro particles at half wavelength intervals along the axis of the transducer.
