Abstract
Inactivation of pathogenic bacteria, Staphylococcus aureus by a high voltage DCDC atmospheric pressure air plasma (APAP) generated by a AC adapter of smart devices such as mobiles and tablets has been performed. 4 kV DC is developed from 5VDC-2A by a high voltage (HV) DCDC converter to be utilize for generation of an arc discharge. This is applied to a coaxial pin with a nozzle configuration, which leads to generate a small APAP. Fourier transform infrared (FT-IR) analysis shows little generation of ozone (O-3) due to conversion of O-3 in high temperature arc discharge region. Current and voltage characteristics, and optical diagnostics are to be detailed along with inactivation test of bacteria. This non-jet air plasma weakly inactivates Staphylococcus aureus.
