Microcannons That Fire Drug-Loaded Nanobullets

Nanoscientists at the University of San Diego have developed microcannons that travel through the body and fire drug-loaded nanobullets at specific targets like tumors.

"Upon application of a focused ultrasound pulse by a piezoelectric transducer, the nanobullets are ejected rapidly from the microcannon," explains Wang. "The mechanism responsible for the propulsion thrust of the nanobullets relies on the momentum associated with the ultrasound-induced spontaneous vaporization of the PFC emulsion droplet into a rapidly expanding microbubble."
