We report the controlled injection of near-isolated micron-sized liquid droplets into a low temperature He-Ne steady-state rf plasma at atmospheric pressure. The H2O droplet stream is constrained within a 2 mm diameter quartz tube. Imaging at the tube exit indicates a log-normal droplet size distribution with an initial count mean diameter of 15 μm falling to 13 μm with plasma exposure. The radial velocity profile is approximately parabolic indicating near laminar flow conditions with the…

The new technique can remotely apply reactive species contained in plasma-activated droplets or bulk liquid to a target that never comes in direct contact with the plasma itself, suggesting the potential to be able to influence biological systems in a controlled way by fine-tuning the chemistry generated from the interaction between non-equilibrium plasma and low volume liquid droplets.
