(a) (i) Trapping results of plasma-driven exosomes re-suspended in the PBS solution with positive potential applied at the base of the pipette after 100 seconds. (a) (ii) Corresponding conductance changes across the pore. (b) (i) Trapping results of exosomes after reversal of the voltage polarity to the negative potential at the base of the pipette after 100 seconds. (b) (ii) Corresponding conductance changes across the pore. (c–d) The blank control experiments without exosomes and the corresponding conductance measurements across the pores. The diameter of the pipette was 1 μm and the applied E-field was 10 V/cm.
