Mycotoxin Detector

I. Product Overview

The handheld fluorescence immunoassay analyzer features a compact, lightweight and small design, making it easy to carry to various field environments for testing, such as emergency rooms, community clinics and even remote areas. Compared with traditional large laboratory equipment, its portability significantly improves testing efficiency and flexibility.

II. Working Principle

Fluorescence immunoassay (FIA) is a novel membrane-detection technology based on the specific antigen-antibody immune response. It uses a strip-shaped fibrous chromatography material with a fixed detection line (coated antibody or antigen) and a quality-control line (anti-antibody) as the stationary phase and the test liquid as the mobile phase; the fluorescently labeled antibody or antigen is fixed on the conjugate pad, and capillary action moves the analyte along the strip. For macromolecular antigens with multiple antigenic determinants (proteins, viruses, pathogenic bacteria, etc.), the 'sandwich' double-antibody immunoassay is typically used: the analyte first binds to the fluorescently labeled antibody in the mobile phase, then binds to the coated antibody at the detection line to form the double-antibody 'sandwich'.

III. Applications

Fluorescence lateral-flow immunoassay is applied in medical diagnosis, oncology research, neuroscience research, drug development, food safety testing, forensic identification and other fields. In drug development it can screen and evaluate drug efficacy and safety; in food safety testing it can detect harmful substances such as additives and residues in food; in forensic identification it can detect and analyze evidence in biological samples.
