Figure 2. Fluorescence-based approaches for surface marker-based EV quantification. (A) ELISA-based EV quantification from blood samples (adapted from ref.[27]); (B) Detection of fluorescent EVs trapped on ultrathin nanopore membrane (adapted from ref.[30]). EVs: Extracellular vesicles; ELISA: enzyme-linked immunosorbent assay; HRP: horseradish peroxidase; NPN: nanoporous silicon nitride; FOV: field of view.
