A team of scientists from the United States has demonstrated that ‘acoustic tweezers’ can be used to trap and manipulate single cells along three dimensions without touching, providing a promising new method for 3D bioprinting.
Numerical simulation results mapping the acoustic field around a particle that shows the physical operating principle for the 3D acoustic tweezers. 3D trapping node in the microfluidic chamber is created by two superimposed, orthogonal, standing surface acoustic waves and the induced acoustic streaming.

The results were published online this week in the Proceedings of the National Academy of Sciences .
“The results provide a unique pathway to manipulate biological cell… Read more
