ABSTRACT: A
different combined effects for helium gas discharge such as: magnetic field
strength, breakdown voltage, applied power, applied pressure, cathode fall
thickness, edge effect, distribution of the electron temperature and density,
and finally exposure time for Staphylococcus aureus substrate over
slides at the cathode edge, are discussed under the influence of cold,
nonthermal plasmas, ultra low pressure, and presence of the magnetic field for
disinfection of bacteria for short exposure times, compatible to International
Commission on Non-Ionizing Radiation Protection, Health Phys (ICNIRP) for
healing applications. Furthermore, analyses of the experimental data of initial
and final densities of cells alive, using survival curves, showed an impressive
inhibitory effect of plasma discharge to the remaining survival of bacterial
ratio under the influence of the magnetic field.
