Surface for detection of interaction between substances and corresponding sensor chip, sensing device and detection method

摘要

Disclosed herein is a surface (1) capable of detecting interaction between substances. This surface has double-stranded DNA (2) which forms the complimentary linkage with single-stranded DNA having one end thereof fixed to the surface, such that the double-stranded DNA (2) dissociates into single-stranded DNA (21, 22) in response to the interaction. Disclosed also herein are a sensor chip and a sensing device, which have the detecting surface as a constituent, and a method for detecting interaction between substances.
