Abstract:
1. A system for processing a nucleic acid sample contained in a liquid, said system comprising (a) a cartridge for processing a liquid nucleic acid sample, said cartridge including (a.1) a chip shaped carrier having an active surface which carries an array of oligonucleotides, said active surface facing an inner surface of a wall of said cartridge, (a.2) a chamber having a narrow interior and including a channel, a portion of said channel lying between said active surface of said chip shaped carrier and the inner surface of said wall, and (a.3) a torsion bar attached to a rigid segment of said wall said rigid segment being adapted to be swung about a predetermined angle back and forth with respect to the active surface about the torsion bar, swinging of the rigid segment in one sense moving one end thereof towards said active surface, and swinging of the rigid segment in an opposite sense moving said one end of that segment away from said active surface, (b) a cartridge holder which is adapted to hold said cartridge in such away that said active surface of said chip shaped carrier lies in a substantially vertical plane, and (c) means for swinging said rigid segment of said wall of said predetermined angle back and forth about said torsion bar in order to cause relative motion of the liquid sample contained in said channel with respect to said active surface of said chip shaped carrier.
