N2 - Herein we present a novel method for microbial disinfection that utilizes the formation of unique Engineered Water Nanostructures (EWNS) generated via electrospraying. The physico-chemical properties of the EWNS such as their size distribution, surface charge, and reactive oxygen species were assessed. The potential of the generated EWNS to inactivate bacteria in air and on surfaces was assessed both quantitatively and qualitatively. Serratia Marcescens (gram-negative) bacteria were used for both the surface and for the air inactivation experiments. Our results show that the EWNS have a size of approximately 20 nm, which is very stable, and carry an average charge of 10 electrons per particle. The results from the surface inactivation of Serratia Marcescens showed that there is more than a 2-log 10 reduction. Similarly the results from the air inactivation showed 50% bacterial removal at steady state.
