Apparatus for transporting substances into living cells and tissues
First Claim
1. An apparatus for introducing one or more particles into at least one cell which comprises said one or more particles associated with means to accelerate said one or more particles to thereby cause said one or more particles to penetrate the at least one cell and whereby at least a portion of said one or more particles becomes incorporated into the interior of the at least one cell, wherein said one or more particles comprise biological substances and have a diameter sufficiently small to penetrate the at least one cell without killing the at least one cell.

Abstract
Inert or biologically active particles are propelled at cell at a speed whereby the particles penetrate the surface of the cells and become incorporated into the interior of the cells. The process can be used to mark cells or tissue or to biochemically affect tissues or tissue in situ as well as single cells in vitro. Apparatus for propelling the particles toward target cells or tissues are also disclosed. A method for releasing particles adhered to a rotor device is also disclosed.
