Title:
BIOSENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/058026
Kind Code:
A1
Abstract:
A biosensor device (1) is provided with a first capturing part (41A, 41B, 41C), a first sensor (51A, 51B, 51C), a second capturing part (42A, 42B, 42C), and a second sensor (52A, 52B, 52C). The first capturing part: is provided with a first binding material that has an activity of binding to a common region of a nucleic acid carrier and a first support that supports the first binding material; and captures the nucleic acid carrier. The first sensor detects a change in ion concentration generated by a first enzyme bound to the nucleic acid carrier captured by the first capturing part. The second capturing part: is provided with a second binding material that has an activity of binding to a variable region of the nucleic acid carrier and a second support that supports the second binding material; and captures the nucleic acid carrier. The second sensor detects a change in ion concentration generated by a second enzyme bound to the nucleic acid carrier captured by the second capturing part.
