Achieving efficient motion of nanomotors in only limited by our capability to power them. In order to do so, it is necessary to develop new propulsion mechanisms, since traditional power sources such as combustion engines and batteries do not scale down efficiently. Interestingly, these limitations have been overcome by using new strategies to convert local environment fuels or external forces into motion at this scales. Fundamental understanding of the energy conversion mechanism of such tiny machines is essential to engender relevant applications. Even though there are many practical advantages of chemical motors, they present drawbacks when applied to biological applications, as they rely on specific environmental conditions or toxic fuels to power them, and they don?t offer a mechanism to modulate their behavior on demand. In contrast, the use of ultrasound fields to wirelessly power nanomotors offers unique advantages; enabling autonomous motion in diverse bio-relevant media and offering on-demand control. . Herein we present the use acoustic powering and actuation of nanomachines for a wide range of biomedical applications, including drug delivery, RNA detection, cargo towing, bactericide, motion control, collective behavior and firing nanobullets from a microcannon.
