Transfection of dextran Alexa Fluor into a targeted HeLa cell by NFP-E at 30 V with 1 second input signal duration: (a) optical image of NFP tip and HeLa cells; (b) fluorescence image of the target HeLa cell in (a) after electroporation and transfection with dextran Alexa Fluor 488; (c) optical image of a second target cell; (d) fluorescence image taken 1 hour after electroporation of the target cell in (c). Note that the cell nuclei in (a) and (c) are stained by Hoechst 33342 (Invitrogen) for better single cell selection.
