Abstract: We describe an improved conductive biocompatible scaffold for electroporation. The biocompatible scaffold comprises biocompatible material (e.g., collagen and/or other extracellular matrix) and incorporates a metal or polymer network or dispersion that conducts an electrical current through the scaffold. The material can adsorb or trap or bind nucleic acids (e.g., RNA or DNA), nanoparticles, proteins and/or small molecules; subsequently cells are placed in proximity to or in contact with the scaffold and an electrical current passed through the scaffold, thereby facilitating cellular entry of the nucleic acids, nanoparticles, proteins and/or small molecules, particularly into those cells that are in proximity of the scaffold.
