Reactive plasma species generated by a surface micro-discharge (SMD) electrode are delivered to the target by diffusion and/or convection. In humid air conditions, the diffusion process is coupled with complicated plasma chemical reactions, which affect the density profiles of bactericidal agents. One may expect that the production of reactive plasma species can be optimized at a certain distance. Our experimental results found the optimum distance for achieving the highest bactericidal efficiency with plasma treatment using an SMD electrode. The optimum distance is about 2-4 mm from the SMD electrode to the target and depends on the geometry of the experiment. The bactericidal efficiency in the plasma-treated area can be improved by a factor of 30 if the bacterial samples are placed at the optimum distance. The results show the predominant role of the long-lived reactive plasma species. It is seen that the diffusion model of multi-plasma species with coupled plasma chemical reactions would be highly important for understanding the bactericidal property of cold atmospheric plasmas and therefore for optimizing cold atmospheric plasma sources for medical and biological applications.
