Acoustic tweezers moves cells in three dimensions, builds structures
Think of what this means for the futures of both health science and nanoparticle constructs.
"In this application we use surface acoustic waves to create nodes where cells or microparticles are trapped," said Tony Jun Huang, professor and The Huck Distinguished Chair in Bioengineering Science and Mechanics. "We can then move the cell or particle in three dimensions to create structures in two or three dimensions."
The trapping nodes are formed by two sets of surface-acoustic-wave generators. When the sound waves from opposite sides meet, they create pressure that catches and positions the particle or cell. Moving the location where the sound waves meet moves the location of the cell or particle. These standing-wave shifts manipulate the tiny objects in two dimensions. The amplitude of the acoustic vibrations controls the movement in the third dimension. The researchers report their work in today's (Jan. 25) issue of the Proceedings of the National Academy of Sciences.
