Biologically inspired micro-robotic swimmers remotely controlled by ultrasound waves.

Lab on a chip Oct 26, 2021
We 3D print micro-robotic swimmers with the size of animal cells using a Nanoscribe. The micro-swimmers are powered by the microstreaming flows induced by the oscillating air bubbles entrapped within the micro-robotic swimmers. Previously, micro-swim...
