Abstract
Laser-induced shock waves have been gaining attention for biological and medical applications in which shock waves influence cell permeation. However, the mechanisms of permeation remain mostly unclear because of the difficulty of observing the transient and dynamic behaviors of the shock waves and the cells. Here we present an all-optical measurement method that can quantitatively capture the pressure distribution of the propagating shock wave and simultaneously monitor the dynamic behavior of cell membranes. Using this method, we find that a sharp pressure gradient causes cell membrane permeation. Our measurement will further advance biological and medical applications of shock waves.
