Custom Quantum Dot Service for Immunofluorescence Detection Technology
Inquiry
Quantum dot immunofluorescence detection technology is a new trend in the rapid development of on-site detection. Quantum dots can also be called semiconductor nanocrystals. As a new type of fluorescent labeling material, quantum dots have excellent optical characteristics such as a wide range of excitation light wavelengths, large Stokes shift, narrow and symmetrical fluorescence peaks, and resistance to photobleaching. It can be applied to improve the detection sensitivity of immunochromatographic methods. Alfa Chemistry specializes in providing customers with these quantum dots for immunofluorescence detection technology, and customizes quantum dot solutions according to customer needs.
Background
As the first of the three major public hazards in the world, drugs seriously threaten and plague human health, development, peace and security. Traditional detection methods for drug addicts include liquid chromatography-mass spectrometry technology, colloidal gold immune lateral chromatography technology and enzyme-linked immunoassay technology. However, there are problems such as relatively low analysis efficiency, need to be equipped with expensive equipment, high operator requirements, and long detection time. Quantum dot immunochromatography technology is a new type of membrane detection technology based on antigen-antibody specific immune reaction and using quantum dot fluorescent probes as markers. This technology uses the strip fiber chromatography material fixed with the detection line (coated antibody or coated antigen) and the quality control line (anti-antibody) as the stationary phase, the test liquid is the mobile phase, and the quantum dot labeled antibody or antigen is fixed on Connecting pad, through capillary action to make the analyte move on the chromatography strip. For drug small molecule antigens, the competition method is usually used, that is, the analyte is first combined with the quantum dot-labeled antibody under the action of the mobile phase, and when it reaches the detection line, it competes with the coated antigen for the quantum dot-labeled antibody, and finally completes through the supporting reader Concentration analysis.

Industrialization Technology System of Quantum Dot Fluorescence Immunochromatography
Quantum dot immunofluorescence detection technology can realize rapid on-site detection of drug addicts on hair samples. By preparing water-soluble red-near-infrared quantum dots with good stability and high quantum efficiency, a process for signal amplification of microspheres to increase the signal-to-noise ratio is established, and directed covalent coupling with antibody molecules to obtain immunofluorescent probes with high immunological activity. Establish a lateral and longitudinal quantum dot immunochromatographic diagnostic technology platform, and construct a quantum dot fluorescent immunochromatographic industrial technology system, which further improves the sensitivity and accuracy of hair drug detection.
