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."
 
Just give us some microbots that can hunt down and kill the queen of an ant nest or keep scorpions out of my kitchen and I'll be pretty happy. I'd pay pretty good for those if they worked worth a damn.
 
Would save us all the exposure to pesticides which are party of the tumor problem so start simpler and be more effective.
