From: Size Specific Transfection to Mammalian Cells by Micropillar Array Electroporation

The working principle of the micropillar array electroporation (MAE).
(a) Schematic of the cell size-specific treatment mechanism (large cells face more micropillars with each providing focused electric pulse during electroporation); (b) a SEM image of 2-μm micropillars; (c) schematic illustration of MAE operation.
