Schematic representation of different EV radiolabelling methods. A) Surface radiolabelling: radionuclide can be incorporated into the EV membrane directly or via a chelator. B) Intraluminal radiolabelling: ionophores allow radionuclides to be transported across the lipid membrane where they can be trapped as their lipophilicity changes or bind to metal chelating biomolecules.
