Are there any bacteria that can receive ultrasound signals? I'm looking for an example of bacteria that could receive ultrasound (at any ultrasound frequency) signal and possibly perform some (re)action afterwards.
Ultrasound frequencies range from 2 to 200 MHz (and up I assume).
To have a wavelength on the order of 3 microns, a 100 MHz wave would be needed.
