Let's hit the micropallets with cells with ultrasound!

The use of ultrasound makes it possible to selectively separate micropallets in a fraction of a second. In addition, the survival rate of cells at the same time exceeds 90%, which is much better than the indicators of any modern technology, the highest achievement of which is 50%
