Characterization of blueberry-derived exosome-like nanoparticles (B-ELNs) (a) size distribution was determined by laser transmission spectroscopy (LTS) and dynamic light scattering (DLS) analysis. The black line shows results obtained with LTS apparatus and the blue line with DLS apparatus (b) morphology of B-ELNs was analyzed under scanning electron microscopy (SEM). The large-field was obtained at 70× magnification (scale bar 200 nm); the insert at 150× (scale bar 50 nm).
