Abstract:
1. Apparatus for exposing a plurality of single cells in succession to a source of activation energy, said apparatus comprising: a disk with a channel formed therein, an outer edge, and a reservoir at the center of said disk capable of retaining a suspension of said cells, said channel commencing at said reservoir and terminating at an outlet port at or adjacent to said outer edge and defining a path of travel whose radial distance from said reservoir continuously increases along said channel; means for rotating said disk in a direction that promotes movement of cells through said channel from said central reservoir toward said outlet port; means for conveying said cells from said reservoir through said channel toward said outlet port; and means for focusing activation energy from said source of activation energy on a portion of said disk as said disk is rotating, said portion defined as an exposure zone and positioned at a fixed radial distance from said reservoir such that said cells pass through said exposure zone in a single-file manner during their passage through said channel.
