Abstract: Various types of biomolecules as the objects of recovery included in a sample solution in minute amounts are separated in accordance with their affinity for various types of probe molecules and readily recovered. A sample solution 8 including biomolecules 7 as the objects of recovery are poured into a microchannel array 6. After the biomolecules 7 are bound to probe molecules which are fixed on the wall of a microchannel in the form of spots and which have a high affinity for the biomolecules 7, a second substrate having periodic protrusions is removed from the microchannel array 6. A portion of the microchannel array 6 that includes a spot in which the probe molecules that are bound to the biomolecules 7, which are the objects of recovery for the first substrate, are fixed is cut with a sharp cutting knife, for example, thereby obtaining a piece that retains on the surface the probe molecules that are bound to the biomolecules 7.

Abstract: In capillary bead arrays, the quality of each of a number of probe beads made by the batch process is non-destructively inspected. Only good probe beads, which are beads having a predetermined quantity of probes of a desired type immobilized on the surface thereof, are selected to be arranged in capillaries, whereby homogeneous and high-quality capillary bead arrays alone can be provided to users. Thus, the reproducibility of biochemical experiments involving capillary bead arrays is significantly increased. Probe beads 401 made by the batch process are one- or two-dimensionally arranged on the bottom surface of a container 402. The probe beads 401 are irradiated with excitation light 403, and the quality of the probe beads 401 arranged on the bottom surface of the container 402 is inspected by spectral analysis. Based on the quality inspection, probe beads judged as defective items are removed from all the probe beads 401, thereby leaving only probe beads judged as good items.

Abstract: A test chip, which allows a number of solution delivery steps much faster and accurate is provided. The test chip incorporates a sample flow path for containing a sample solution, a reaction flow path for inducing a predetermined reaction with the sample solution, a waste drain path for receiving the used sample, and the washing solution flow paths for containing washing solutions. The reaction flow path contains a plurality of beads having probes of mutually different types fixed thereon. The sample flow path, washing solution flow paths, and sample waste drain path have their respective solution detector units. The solution detector unit detects whether the solution is fed to the path. The detector units adjoiningly provided in the adjacent paths are arranged collinearly.
