Lance array nanoinjection stepwise process. 1 Staging the lance array in the solution containing the desired molecular load. 2 Electrical attraction of the molecular load onto the lances. 3 Physically penetrating the cell membrane of target cells and electrical repulsion of the molecular load into the cytoplasmic space. 4 Removal of the lance array, leaving the molecular load in the intracellular space of target cells
