Histological examination of skin after electroporation in vivo. (A) Representative images obtained by stereo microscope are shown for untreated mouse skin and skin 0 h and 3 h after electroporation using 20 pulses by the ePatch in vivo. (B) Representative images obtained by brightfield microscopy of untreated mouse skin and skin electroporated with pulses by MEA combined with conventional millisecond electroporator (30 V, 55 ms) or ePatch with 20 pulses of microsecond duration. The skin was harvested 12 h after electroporation and H&E stained for examination.
