Patent ID: 7182916

Claim:
A device for micro-particle array fabrication, comprising: a container having one-dimensionally or 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; at least one capillary having an inner diameter, which prevents passage of any one of the micro-particles therethrough, having an opening at one end, the opening accommodating thereon only one of the micro particles; a first pressure applying means applying a negative pressure or a positive pressure to the capillary; a vessel for receiving the micro-particles and forming a micro-particle group; a moving means moving the opening of the capillary holding the micro-particle to a prescribed position of the vessel; a computer for controlling the movement and the position of the capillary, and the pressure to be applied to the capillary; and a second pressure applying means applying a negative pressure to the vessel when the first pressure applying means applies the positive pressure to the capillary.
