N2 - Decontamination treatments of surfaces are performed on bacterial spores, albumin and brain <br/>homogenate used as models of biological contaminations in a low-pressure, inductively <br/>coupled plasma reactor operated with water-vapour-based gas mixtures. It is shown that <br/>removal of contamination can be achieved using pure H2O or Ar/H2O mixtures at low <br/>temperatures with removal rates comparable to oxygen-based mixtures. Particle fluxes (Ar+ <br/>ions, O and H atomic radicals and OH molecular radicals) from water vapour discharge are <br/>measured by optical emission spectroscopy and Langmuir probe under several operating <br/>conditions. Analysis of particle fluxes and removal rates measurements illustrates the role of <br/>ion bombardment associated with O radicals, governing the removal rates of organic matter. <br/>Auxiliary role of hydroxyl radicals is discussed on the basis of experimental data. The <br/>advantages of a water vapour plasma process are discussed for practical applications in <br/>medical devices decontamination.
