Light-induced active ion transport in graphene oxide membranes

Recent research in nanofluidics has adopted reconstructed layered two-dimensional (2D) sheets as a promising material platform for nanofluidics. These membranes contain a high volume fraction of interconnected 2D nanochannels. In new work, researchers demonstrate a coupled photon-electron-ion transport phenomenon through graphene oxide membranes. It shows a straightforward way on how to power the transport in 2D layered materials using the energy of light.
