nanobullet

plural nanobullets

1. A nanoscale bullet, typically used to administer medicine.

   When an ultrasonic beam is fired at the microcannons, the emulsion evaporates, expanding rapidly into gas. This creates enough force to push the nanobullets out at velocities reaching several metres per second.

   PFC vaporizes when hit with an ultrasound pulse, producing rapidly expanding gas bubbles that "fire" the nanobullets out of the microcannons at speeds on the order of meters per second -- and the fluorescent microbullets light up to show exactly where they landed in the tissue target.

   A nanobullet comprising of multifunctional Janus nanocomposites (a head of magnetic Fe₃O₄ and a body of mesoporous SiO₂ containing doxorubicin) is reported to be a safe and efficient treatment for liver cancer.
