"The researchers' most recent version of acoustic tweezers involves a microfluidic device that uses acoustic wave generators to produce sound waves along the edges of the device. The device's design allowed researchers to manipulate where the waves would meet along each of the three axes. At these meeting points, the waves formed a 3-D trapping node that captured individual cells. The researchers could then further manipulate the acoustic waves to move and place cells."
This sounds like science fiction to me , this is truly an amazing time to live . Using sound waves to move cells in 3D space is a huge medical breakthrough and can dramatically help with tissue growth. To read more about this article please go here .
