Title:
LABEL-FREE BIOCHEMICAL REACTION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/052146
Kind Code:
A1
Abstract:
A label-free biochemical reaction detection method, comprising: S100, filling a pipe (4) with an electrolyte solution; S200, selecting receptor molecule A (6) capable of reacting with target molecule B (7) and modifying receptor molecule A (6) on the inner wall of the pipe; S300, introducing a dispersed phase into the pipe (4) for same to form a dispersed phase area (3), and retaining the dispersed phase area (3) in the pipe (4); S400, measuring and recording a contact angle of the dispersed phase area (3) in the pipe (4) and the total resistance of the solution in the pipe (4) before reacting with the target molecule (7); S500, introducing a solution or fluid possibly containing target molecule B (7) into the pipe (4) and reacting with receptor molecule A (6); S600, repeating step S300 to step S400, comparing changes in the contact angle and resistance of the dispersed phase before and after the reaction; if the change is great, then the solution or fluid contains target molecule B (7); and if not, same does not contain target molecule B (7). This serves as an inexpensive, highly sensitive, quick, and label-obviating label-free detection method for a biochemical molecular reaction.
