L'électroporation est une méthode d'introduction d'ADN dans des cellules. Techniquement, on applique un champs électrique sur les membranes qui sont ainsi déstabilisées, et l'ADN présent dans l'espace extra-cellulaire peut rentrer dans les cellules en migrant vers le pôle positif de la charge, étant lui-même chargé négativement.
