Abstract

In order to provide a member for producing a probe array that allows producing desired probe arrays immediately once the probe arrangement is established, and to provide a probe array producing method that uses this member for producing a probe array, the pieces F₁, F_{2 . . .} F_n are produced by cutting the members M₁, M₂ . . . M_n for producing a probe array, and a predetermined number of pieces F₁, F₂ . . . F_n are detached from a release sheet 13 and are attached via the adhesive layer 12 onto the supporting member 2a at predetermined locations.

Claims

1. A member for producing a probe array comprising a substrate,

probes immobilized on a first region of the surface of the substrate and

an adhesive layer provided on a second region of the surface of the substrate.

2. The member for producing a probe array according to claim 1, wherein the substrate is a sheet-like substrate, the first region is positioned on one face of the sheet-like substrate, and the second region is positioned on the other face of the sheet-like substrate.

3. The member for producing a probe arrays according to claim 1 or 2, wherein only one type of probes are immobilized on the first region.

4. A probe array comprising

a supporting member and

the member for producing a probe array according to any one of claims 1 to 3, or a piece thereof, arranged on the surface of the supporting member,

wherein the member for producing a probe array or the piece thereof is attached via the adhesive layer on the supporting member in such a way that the probes are exposed.

5. The probe array according to claim 4, wherein the supporting member is a tubular member, and the member for producing a probe array or the piece thereof is attached on the inner face of the tubular member.

6. The probe array according to claim 4, wherein the probe array further comprises a tubular member, and the supporting member is housed in the hollow portion of the tubular member in such a way that the probes are exposed to the hollow portion of the tubular member.

7. The probe array according to claim 6, wherein a spacer for preventing contact between the outer face of the supporting member and the inner face of the tubular member is provided on the outer face of the supporting member or on the inner face of the tubular member.

8. A method for producing a probe array comprising a supporting member, and the member for producing a probe array according to any one of claims 1 to 3, or a piece thereof, arranged on the surface of the supporting member,

the method comprising a step of attaching via the adhesive layer the member for producing a probe array or the piece thereof on the supporting member in such a way that the probes are exposed.

9. The probe array producing method according to claim 8, wherein the supporting member is a tubular member, and in the step the member for producing a probe arrays or the piece thereof is attached on the inner face of the tubular member.
