microcannon

Definitions

A microscopic cannon, typically used to inject medicine into a body.

Examples

“The microcannon starts with a membranous polymer film. […] 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 battery of several microcannons can be used to fire the drug cargoes at different times and different depths.”

“The microcannon was seen moving at about a micron per second, it was about 15 microns long, and the high speed⟳ photograph was done in water (density of 1 kg/L, viscosity of about 0.001 pascal seconds).”
