Nanoscale Corona Discharge in Liquids, Enabling Nanosecond Optical Emission Spectroscopy

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 of femtoliter volumes of liquid with a one-micrometer spatial resolution.
