Researchers can now manipulate cells using surface acoustic waves


This new method involves employing a microfluidic device to generate sound, creating the 3D ‘trapping node’ that allows cells to be herded around. Cells can be picked up and dropped off, or even placed on top of other cells. There is not needed any invasive contact, tagging or biochemical labeling. This way, new possibilities for research and applications are permitted in areas as regenerative medicine, neuroscience, tissue engineering, bio-manufacturing and cancer metastasis. The acoustic  tweezers are working as ‘building blocks’ offering precision and leading the way in bioprinting to eventually creating entire organs. The team of engineers who created this technology includes Feng Guo, Zhangming Mao, Yuchao Chen, Zhiwei Xie, James P. Lata, Peng Li, Liqiang Ren, Jiayang Liu, Jian Yang, Ming Dao, Subra Suresh, and Tony Jun Huang.
