Title:
SMELL SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/216192
Kind Code:
A1
Abstract:
Provided is a smell sensor that obtains sensitivity resulting in more stable quantification and can be produced with inexpensive materials. This smell sensor 1 is provided with at least one pair of electrodes 2, a conductor 4, a G protein-coupled receptor 5, and a detection unit (ammeter A). The conductor 4 bridges the at least one pair of electrodes 2 and is electrified. The G protein-coupled receptor 5 is adhered to the conductor 4. The detection unit uses a change in the electrification state of the conductor 4 to detect a change in the three-dimensional structure of the G protein-coupled receptor 5 when the G protein-coupled receptor 5 receives a component to be measured.
