Abstract: A method and system of delivering a charged cargo, such as a biomolecule, to a target structure, such as cells, exosomes, other vesicles or micelles, using an electroactive porous membrane. This method comprises contacting an electroactive porous membrane with a fluid flow toward the membrane. The fluid contains charged biomolecules and the membrane and biomolecules are oppositely charged so that the biomolecules in the fluid are trapped on the membrane as the fluid flows through the pores of the membrane. Acceptor cells of interest are pinned to the membrane by the flow of the fluid, thereby aggregating the cells onto the membrane in close proximity to the trapped biomolecules. Finally, the acceptor cells are permeabilized.
