High-Performance Ultrasonic Tweezers for Manipulation of Motile and Still Single Cells in a Droplet

The manipulation of motile and still single cells with the simultaneous features of selective trapping, 3-D path free transport, position-controllable release and little heat damage has been a significant challenge. We developed an ultrasonic method for capturing motile and still single cells with the aforementioned features in a droplet. During manipulation, a micromanipulation probe (MMP), which vibrated linearly with a trajectory parallel to a silicon substrate, was immersed in the droplet and was not in contact with the substrate.
