Abstract:

Flow virometry (FVM) represents a cutting-edge technological approach leveraging flow cytometry for the precise detection and analysis of individual virus particles and their unique characteristics. This innovative method offers a novel means of detecting, quantifying, and characterizing individual virus particles. FVM enables the determination of various parameters including the concentration of intact virus particles, the abundance of specific target antigens present on the virus surface, and the relative diameter of the viruses. Within the field of technique, FVM extends beyond virus analysis, allowing for the effective detection and characterization of exosomes and microvesicles originating from cells. With the continuous development and optimization of instruments, fluorescent dyes and labeling strategies, FVM has been widely used and studied. This paper summarizes the development history of FVM, as well as the common labeling methods and application fields of viruses and other microparticles, aiming to provide reference for the further application of FVM in virology, immunology, biomedics and other research fields.

Key words: flow virometry, flow cytometry, virus and exosome labeling
