On page 392, Valentina Benfenati, Maria Rosa Antognazza, Michele Muccini, and colleagues show how the photostimulation of a semiconducting polymer blend modulates the ion channel conductance of astrocytes cultured on top of the device. The device can be used as a selective tool to study ion channel conductances in non-excitable cells.
