1. A method for ultrasonically cleaning an internal body part comprising:
providing into a cavity of a living body a liquid;
providing into the cavity nanoparticles which have a morphology which includes one or more sharp shapes capable of piercing infectious agents;
generating ultrasonic waves in the liquid with the nanoparticles suspended therein for a defined period of time, wherein said ultrasonic waves are used to generate imploding cavitation bubbles, creating micro-jets in said liquid when said nanoparticles are suspended therein, resulting in bombarding surfaces of said internal body part with said nanoparticles to clean and disinfect said surfaces of said internal body part; and
removing from the cavity the liquid with the nanoparticles suspended therein, after the defined period of time has lapsed.
