Description

technical field [0001] The invention relates to the field of biochemical sample detection instruments, in particular to a portable biochemical rapid detection system based on quantum dot fluorescent labeling, which combines the quantum dot fluorescent label analysis method with mechanical and electronic control to form an automatic detection device system. Background technique [0002] Fluorescence is a phenomenon of photoluminescence. When a light source shines on certain substances, the so-called fluorescein, it emits excited light of different wavelengths; when the light source is removed, the excited light emitted by fluorescein also disappears. Using fluorescein to mark the analyte by certain means, and then based on the linear relationship between the fluorescence intensity emitted by fluorescein and the concentration of the analyte, is the detection principle of the so-called fluorescence spectroscopic analysis. [0003] Compared with other methods, fluorescence spec...

Problems solved by technology

[0003] Compared with other methods, fluorescence spectroscopy has the advantages of high sensitivity, good specificity, and rapid detection, but the nature of fluorescein itself will have a relatively large impact on the detection results. The fluorescence lifetime is short or the wavelength is similar to the background light. Negatively affect the final test result
