“…With the help of enrichment technology, e.g., bead-based enrichment [ 88 , 89 ], enrichment by specially designed probes [ 90 ], and droplets-encapsulating technology [ 91 ], the analysis of species of virus has become feasible. A virus can be captured, trapped, and lysed, and the nucleic acid can be amplified and detected, which has expanded the potential application of flow virometry.…”
