Abstract

The invention discloses a three-dimensional lateral flow test paper detector, a preparation method and a detection method. The three-dimensional lateral flow test paper detector comprises a transparent round tube (1) and lateral flow test paper (2), wherein a sampling marker line (3) is arranged on the transparent round tube (1) used for loading the lateral flow test paper (2); the lateral flow test paper (2) used for detection is rolled into a cylinder to be arranged in the transparent round tube (1) and tightly attached to the inner wall; the lateral flow test paper (2) comprises a sample pad (4), a conjugate pad (5), a detection pad (6) and an absorbent pad (7) connected in sequence in a direction from the orifice to bottom of the transparent round tube (1); the sample pad (4), the conjugate pad (5), the detection pad (6) and the absorbent pad (7) respectively have different widths, and two adjacent pads are partially coincided.

Description

technical field [0001] The invention relates to the technical field of biological test paper detection, in particular to a three-dimensional lateral flow test paper detection instrument, a preparation method and a detection method. Background technique [0002] Lateral flow test strips are widely used in instant diagnosis in the fields of food safety, medical diagnosis and environmental monitoring due to its characteristics of fast detection, portability, simple operation and low cost. Generally, the lateral flow test paper analyzer consists of five parts: sample pad, connecting pad, detection pad, absorbent pad and adhesive backing board. It mainly uses the principle of antigen-antibody specific reaction or nucleic acid base pairing to capture the target with chromogenic particles on the detection line and capture chromogenic particles on the control line. When a certain amount of chromogenic particles accumulate on the detection line or the control line, and the color app...
