Method and the device for micro-particle array fabrication

A device for micro-particle array fabrication, comprising:

• a container having two-dimensionally arrayed different individual holders, the holders holding therein a plurality of micro-particles having different kinds of probes, which will bind to biomaterials, immobilized thereto, and having roughly the same outer-diameter, according to the kinds of the probes;
• a plurality of capillaries in a number equal to the number of rows of the two-dimensionally arrayed holders, and arrayed at a spacing equal to the spacing between the rows, the capillaries each having an inner diameter not allowing passage of only one of the micro-particles therethrough, each having an opening at one end, and being controlled under negative pressure, the capillaries being for inserting the openings into their respective two-dimensionally arrayed holders on a row-by-row basis, and holding only one of the micro-particles on each of the openings;
• a means for applying the negative pressure thereto;
• a vessel for receiving the micro-particles in a prescribed order on a row-by-row basis, and forming a micro-particle group;
• a means for moving the openings of the capillaries each holding the micro-particle to their respective prescribed positions of the vessel for forming the micro-particle group;
• a means for applying positive pressure to the capillaries upon moving the capillaries to their respective prescribed position;
• and a computer for controlling the movement and the position of the capillaries, and the pressures to be applied to the capillaries.
