Aligning Cells with Ultrasound for Bioprinted Tissues
May 21, 2019 | Terry Sharrer
Biofabrication relies on several means for aligning cells for 3D printed tissues, now including acoustophoretics. Researchers at North Carolina State University have used ultrasound to replicate the natural arc shape of a knee meniscus. “The technique relies on a special chamber within which the 3D printing process takes place. The chamber generates ultrasound waves that flow from one wall toward the opposite, bouncing back and creating standing waves. The standing waves motivate the cells to align along with them, and as a structure is printed and cells positioned within, they can be made to take any orientation desired.” MORE
