Micro-object manipulation by acoustically exited identical twin bubbles: (a) Initial state; (b) When identical bubbles on the tips of a U-shaped rod are acoustically exited, they simultaneously oscillate and generate microstreaming, which, in turn, pushes an object; (c) The rod moves to the right, and the object is carried by the microstreaming; (d) The excitation is turned off and the rod moves to the left; the object is released from the bubbles and remains at its position.
