Fluorescent microsphere detection principle

The fluorescent markers are fluorescent microspheres made of specially packaged lanthanide elements and their chelates. The fluorescence intensity is much higher than that of ordinary fluorescent markers, which greatly improves the sensitivity of detection.

There is a large Stokes shift between the excitation wavelength and emission wavelength of lanthanide elements and their chelates, which reduces the interference of specific stray light caused by the excitation light on detection and improves the stability of fluorescence detection; at the same time, the fluorescence lifetime is long, eliminating It eliminates the interference of fluorescent substances in the environment to the analyte, and the fluorescence excitation wavelength is wider and the emission wavelength is narrower. It has the advantages of low background, high resolution and strong specificity.
