  • Method and apparatus for controlling, orienting and analyzing biological cells in liquid suspension
    Patent number: 4280623
    Abstract: A liquid flow system contains suspended biological cells for the purpose of orienting them, spacing them from each other and analyzing the cells. Many biological cells are not of spherical shape but may be disk-like or rod-like in appearance. The present flow system includes means for orienting the cells with respect to the liquid flow and for either centering them or displacing them into a desired plane within the fluid flow. The cells are electrically charged, suspended in a dielectric fluid and deflected by a suitable electric field. Optionally an image analysis may be performed.
