Electroporation by concentric-type needle electrodes and arrays.

The efficacy of genomic medicine depends on gene transfer efficiency. In this area, electroporation has been found to be a highly promising method for physical gene transfer. However, electroporation raises issues related to electrical safety, tissue damage, and the number of required wounds. Concentric-type needle electrodes seek to address these issues by using a lower bias (10V), a single wound, fewer processing steps, and a smaller working area (≈10mm
