How electric fields pierce cell membranesPublication of the Chemistry Laboratory in the journal PNAS on March 7, 2023. Communication of the CNRS-INC on March 28, 2023. Electroporation consists of perforating the cell membrane with an electric field to pass a therapeutic substance through it. A team from the Chemistry Laboratory (CNRS/ENS de Lyon/Claude Bernard Lyon 1 University) and their colleagues from the University of Freiburg im Breisgau have published in the journal PNAS some essential elements for understanding this widely used but still little understood phenomenon.
