When a cell is very close to the capillary wall, a narrow passage between the cell and the capillary wall is formed for the electric current to pass through. This narrow passage is allocated a higher voltage because liquid resistance is inversely proportional to the cross-sectional area. The effective electroporation surface on the cell is also increased. The capillary effect (CE) can be similarly achieved in a non-capillary solution by placing cells at a high concentration allowing them to be each other\u2019s next insulator.<img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-259 alignright\" src=\"https:\/\/www.celetrix.com\/wp-content\/uploads\/2024\/09\/VS-CAPILLAY-E.jpg\" alt=\"\" width=\"360\" height=\"316\" \/><\/div><div class=\"col-sm-12 col-md-5-5\"><img decoding=\"async\" src=\"http:\/\/www.celetrix.com\/wp-content\/uploads\/2021\/11\/20180326165323_118.jpg\" alt=\"\" \/>The capillary effect is very sensitive to the distance between the cell and the capillary wall.
