Micro/nano Manipulation Using Acoustic Waves

Dr. Xiaoyun Ding

University of Colorado Boulder

Abstract

Manipulation of particles in micro and nano scale has been invaluable in a variety of scenarios in applied physics, chemistry and biomedicine. Acoustic microfluidics has emerged as a powerful and novel platform for micro/nano manipulation in many applications recently due to its advantages in versatility, low cost, easy to integrate and manufacture, miniaturization, energy efficiency, etc. Here, I will first introduce the development of acoustic tweezer which can manipulate objects from nano to mm scale on a chip. I will then report our most recent breakthroughs on acoustic manipulation, including (1) acoustic thermal shift assay for protein manipulation and characterization, (2) internal structure manipulation of colloids using acoustic waves, and (3) staged assembly of colloids.
