Abstract
A bead array chip manufacturing process for manufacturing a bead array chip having plural kinds of beads arrayed in a predetermined order in, in a container having a plurality of first channels disposed substantially in parallel with each other and a second channel crossing the plurality of first channels, each of the first channels. The process including lowering a capillary inserted in the second channel and sucking and retaining one bead in one end of the capillary, lifting the capillary to position the beads retained in the one end of the capillary in a desired channel of the plurality of first channels, terminating the suction of the capillary, and generating a uniflow of a fluid in the second channel.

A bead array chip manufacturing process for manufacturing a bead array chip, the bead array chip having plural kinds of beads arrayed in a predetermined order within a container, the container having a plurality of first channels disposed substantially in parallel with each other and a second channel crossing the plurality of first channels, the process comprising:
- lowering a capillary inserted in the second channel;
- and
- initiating suction of the capillary, thereby retaining a bead at one end of the capillary;
- lifting the capillary to position the capillary such that the bead retained at the one end of the capillary is disposed in a desired channel selected from the plurality of first channels;
- terminating the suction of the capillary;
- and
- generating a flow of a fluid in the desired channel, thereby releasing the bead into the desired channel.
A bead array chip manufacturing process for manufacturing a bead array chip, the bead array chip having plural kinds of beads arrayed in a predetermined order within a plurality of containers, each container having a plurality of first channels disposed substantially in parallel with each other and a second channel crossing the plurality of first channels, the process comprising:
- disposing the plurality of containers proximate to a plurality of capillaries, wherein each capillary is assigned to a corresponding container;
- simultaneously driving each of the plurality of capillaries in the second channel of the container assigned to the capillary;
- initiating suction of the plurality of capillaries, thereby retaining a bead at the end of each capillary;
- lifting the capillaries in order to position the capillaries such that each bead retained at the one end of a capillary is disposed at an intersection of the second channel and a desired channel selected from the plurality of first channels in the container assigned to the capillary;
- terminating the suction of the capillaries;
- and
- generating a flow of a fluid in the desired channels, thereby releasing the beads into the desired channels.
