Detection and quantification of Ascorbic Acid in nanovesicles were performed using a fluorometric Ascorbic Acid Assay Kit (Sigma-Aldrich, St. Louis, MO, USA). Samples were diluted in ascorbic acid buffer in a 96-well plate and subsequently to each well was added a catalyst and then reaction mix (the reaction mix is composed of an ascorbic acid buffer, ascorbic acid probe and ascorbic acid enzyme mix). After 5 min of incubation, fluorescence was read in a microplate reader at Ex/Em = 535/587 nm.
