From: Strategies to overcome the main challenges of the use of exosomes as drug carrier for cancer therapy
Characterization of exosome using two most advanced strategies: (i) nanoparticle tracking analysis NTA and (ii) fluorescent microscope FM. The developed NTA strategy allows exosomes to be tracked through a video file tracker and determine the speed and movement of the exosomes. At the same time, a fluorescent microscope FM can be used to study exosomes in vitro and in vivo by marking a specific protein on the membrane of an exosome with a fluorescent dye
