Abstract
In this work, for the first time, we visibly generated a lightning through nanoporous membrane in micro/nanofluidic platform. Firstly, a micro bubble was formed by Joule heating inside a microchannel with an application of electric field (E) of 100 V/cm. Secondly, vapor phase was changed into plasma phase and bright light was emitted at |E| = 500 V/cm. Finally, it was observed that emitted light propagated through the perm-selective nanoporous membrane along with strong cation flux. These findings would have a scientific significance for the visualization of cation trajectories inside the nanoporous membrane.
