Description

technical field

[0001] The invention belongs to the field of medical examination, and relates to a fluorescent latex quantitative chromatography diagnostic test strip and a preparation method thereof. Background technique

[0002] In immunoassay, methods such as radioimmunoassay, enzyme-linked immunosorbent assay (ELISA) and colloidal gold labeling are mainly used at home and abroad to achieve quantitative or qualitative detection. These methods all have defects in varying degrees. Taking the immunocolloidal gold chromatography test strip widely used at present as an example, there are following deficiencies:

[0003] (1) Colloidal gold is a kind of nanoparticle. It is difficult to prepare colloidal gold nanoparticles, and it is difficult to control the particle diameter uniformly.

[0004] (2) A strong reducing agent is used in the colloidal gold labeling process, and at the same time, it is exposed to heavy metal ions, which has a certain impact on human health and safet...
