Dielectric barrier discharge microplasma has various industry applications such as surface treatment, NOx removal, flow control ore biomedical applications. Transdermal drug delivery procedure could be enhanced by microplasma. Along with this procedure skin treatment in order to remove harmful bacteria is necessary. One of these harmful bacteria which lives on human skin is Staphylococcus Aureus . Microplasma was used for the sterilization of Staphylococcus Aureus . Argon, oxygen and air were used as discharge gases. The sterilization process is mainly carried out by the reactive oxygen species. Thus the highest sterilization rates were obtained by using as discharge gas air or a mixture of argon and oxygen. The applied voltages were sine wave and pulse. In the case of sine wave the ozone generation is higher thus a pulse powered microplasma discharge is preferred.
