Frontispiece

Yusuke's work has been selected as a frontispiece of Advanced Science!

Conformal SWCNT Nanofilm Electrodes for Plant Electrophysiology

SWCNT nanofilm electrodes conformally attached to a leaf surface, where trichomes pierce through the ultrathin film to achieve intimate contact. The transparent, water-vapor-permeable, and water-resistant electrodes enable long-term, non-invasive electrophysiological monitoring of plants. More details can be found in the Research Article by Toshinori Fujie and co-workers.
