Figure 1: Example of dynamic light scattering test results showing the contribution of exosome-sized particles (radii below 50 nm), microparticles (radii 50–550 nm), platelets, and microaggregates (radii above 550 nm). (a) Homogeneous platelets (few or no microparticles, platelets with predominantly discoid shape with low polydispersity, and narrow blue peak). (b) Heterogeneous platelets (many microparticles, platelets with high polydispersity, and broad blue peak).
