Nanoscale corona discharge in liquids, enabling nanosecond optical emission spectroscopy

Abstract

My corona! A nonthermal corona discharge inside a liquid medium around electrodes with ultrasharp tips or elongated nanoparticles allows simultaneous chemical analysis of multiple dissolved elements within nanoseconds. The proposed optical emission spectroscopy method can be applied for ultrafast time-resolved multielemental analysis off emtoliter volumes ofliquid with a one-micrometer spatial resolution.
