The present invention uses aerosol beam technology to accelerate either wet or dry aerosol particles to speeds enabling the particles to penetrate living cells. Aerosol particles suspended in an inert gas are accelerated to a very high velocity during the jet expansion of the gas as it passes from a region of higher gas pressure to a region of lower has pressure through a small orifice. The accelerated particles are positioned to impact a preferred target for, example, a plant or animal cell or bacterial culture.

Why it's free to use
- Filed January 10, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 10, 2012.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
