Abstract

A sensor device enabling quick and uniform dissolution of reagents is provided. The sensor device includes a holding member having a liquid sample holding section for holding a liquid sample containing an analyte. A reagent that reacts or interacts with the analyte in the liquid sample and an effervescent agent that effervesces upon contact with the liquid sample are held at a position of the holding member where they are to come into contact with the liquid sample introduced into the liquid sample holding section.

Claims

1. A sensor device comprising a holding member, said holding member having a liquid sample holding section for holding a liquid sample containing an analyte,

wherein a reagent that reacts or interacts with the analyte in said liquid sample and an effervescent agent that effervesces upon contact with said liquid sample are held at a position of said holding member where said liquid sample and said effervescent agent are to come into contact with said liquid sample introduced into said liquid sample holding section.

2. The sensor device in accordance with claim 1, wherein said effervescent agent effervesces by producing carbon dioxide.

3. The sensor device in accordance with claim 1, wherein said effervescent agent comprises at least a hydrogen carbonate or a carbonate.

4. The sensor device in accordance with claim 1, wherein an organic acid is further held at said position of said holding member.

5. The sensor device in accordance with claim 4, wherein said organic acid is at least one selected from the group consisting of maleic acid, maleic anhydride, succinic acid, succinic anhydride, phthalic acid, phthalic anhydride, citric acid, fumaric acid, and tartaric acid.

6. The sensor device in accordance with claim 1, wherein said liquid sample is a liquid derived from a living body.

7. The sensor device in accordance with claim 1, wherein said reagent is an enzyme or an antibody.

8. The sensor device in accordance with claim 1, wherein at least a part of an inner face of said liquid sample holding section is hydrophilic.
