Carnegie Mellon Researchers Use Acoustic Tweezers to Move Bioprinted Cells

As bioprinting progresses, researchers are looking toward the best ways to keep cells alive. A team at Carnegie Mellon University has recently released their findings regarding the use of acoustic tweezers in their paper, ‘Three-dimensional manipulation of single cells using surface acoustic waves.’ Recently published in the Proceedings of the National Academy of Sciences, this paper explains how researchers are able to use the tweezers to move cells without damaging them, using sound waves to capture them and then manipulate them, picking them up, dropping them off in other ‘locations,’ as well as even layering them on top of other cells--thus allowing for 3D printing--all performed in a contact- and contamination-free manner.
