Extracellular vesicle visualisation and quantification. a TEM observation of whole-mounted EV purified from human serum by precipitation. b NanoSight trace for representative sample is shown. Black trace indicates EV concentration with increasing particle size, and blue trace shows cumulative percentage of EV with increasing particle size. c Concentration of EV (30–120 nm) in stroke (n = 48) and non-stroke (n = 9) patients. Horizontal bar represents mean. Unpaired two-tailed Student’s t test assessed statistical significance
