Handheld mycotoxin detector

The handheld mycotoxin detector is compact, lightweight, and small in size, making it easy to carry to various field environments for testing, such as emergency rooms, community clinics, and even remote areas. Compared to traditional large laboratory equipment, its portability significantly improves testing efficiency and flexibility.

Fluorescent immunoassay technology is a novel membrane-based detection technique based on antigen-antibody specific immune reactions. This technology uses strip-shaped fiber chromatographic materials with fixed detection lines (coated with antibodies or antigens) and control lines (anti-antibodies) as the stationary phase, with the test solution as the mobile phase. Fluorescently labeled antibodies or antigens are fixed to the connection pad, and the analyte moves along the chromatographic strip via capillary action.

For large-molecule antigens (proteins, viruses, pathogenic bacteria, etc.) with multiple antigenic determinants, the “sandwich” type double-antibody sandwich immunochromatography method is typically used. In this method, the analyte first binds to the fluorescently labeled antibody under the action of the mobile phase, and then binds to the coated antibody at the detection line to form a “sandwich” structure with the double-antibody sandwich.

Fluorescent immunoassay is applied in various fields such as medical diagnosis, tumor research, neuroscience research, drug development, food safety testing, and forensic identification.
① In drug development, handheld fungal toxin detectors can be used to screen and evaluate the efficacy and safety of drugs.
② In food safety testing, harmful substances such as additives and residues in food can be detected.
③ In forensic identification, it can be used to detect and analyze evidence in biological samples.
