Abstract
A method and an apparatus for the treatment of particles or biological cells are disclosed, wherein the particles or cells are precipitated or ascended depending on the specific gravity of a liquid used, and the particles or cells are handled with the aid of a holding plate. A method and an apparatus for the fusion of particles or cells are also disclosed, wherein an electric voltage is loaded on a position between electrodes in a microchamber to fuse the particles or cells held in the microchamber.
Claims3
A method for transferring biological cells to a plurality of microchambers arranged in a pattern, which comprises supplying the biological cells to a first solution in contact with a plurality of holding means including absorption ports for retaining individual biological cells, said first solution having a specific gravity which causes the biological cells to move towards said holding means;
- holding an individual biological cell at each of said absorption ports of said holding means;
- removing other cells not held by said absorption ports of said holding means by supplying a second solution, said second solution causing the other cells to move away from said holding means and transferring the held biological cells within the absorption ports of said holding means to the plurality of microchambers arranged in a pattern.
