  • Title: Acoustic Streaming Eddies in Ultrasonic Nano Manipulations
  • Abstract:
    Nano manipulation technology has wide potential applications in the micro/nano measurement and assembling, fabrication of high-end microelectronic and photonic devices, high–sensitivity sensing, treatment of biomedical samples, etc. Ultrasonic nano manipulation is a new manipulating technology which emerged in 2012. It has the merits such as low temperature rise at the manipulating area, diversified manipulating functions, capability to integrate multiple manipulating functions in one device, compact and light device structure, etc. So far it has been utilizing the acoustic streaming eddies to trap, position, rotate, orientate and concentrate nanoscale entities. Proper acoustic streaming eddies are the key to implement and improve various nano manipulation functions. After proposing the ultrasonic methods for nano manipulations in recent years, the author’s group has been researching the features of the acoustic streaming fields for various nano manipulations, and the effective methods to generate and control the acoustic streaming eddies. In this report, we demonstrate the features of the acoustic streaming eddies for the contact-type and noncontact-type nano trapping, nano rotary driving and nano concentration, and give the methods to generate and control the acoustic streaming eddies.
