a Comparison between Abs_MNWs and conventional methods (Exoquick and Invitrogen) for exosome isolation. b NTA results demonstrating the ability of nanowires to isolate exosomes from the plasma of lung cancer patients versus that of the Exoquick and Invitrogen methods. c Comparison of exosome sandwich ELISA. The exosomes were isolated from lung cancer patients using Abs_MNWs and conventional methods (Exoquick and Invitrogen). The Abs_MNWs showed excellent performance in retrieving exosomes, particularly with CD9/CD81 exosomal specific proteins. The data shown represent the mean ± SD of data from three independent experiments
