      <Pgraph>Successful and reliable sterilisation of medical instruments is basic requirement in every hospital and in every medical practice. Conventional sterilisation methods are often reaching their limits since new materials used in modern medical technology such as plastics cannot withstand the heat during the autoclaving or their surface is strongly modified and etched in cold sterilisation using chemicals. Plasma sterilisation offers the possibility of effective sterilisation that is however at the same time friendly to the treated object. Desired effects can be very selectively achieved by the proper choice of the plasma generation scheme and gas mixture used. </Pgraph>
      <Pgraph>The interaction of plasmas with bacteria, viruses, and pathogenic molecules is studied in the European project BIODECON, which is coordinated by the <Mark2>Center for Plasma Science and Technology</Mark2> (CPST) at Ruhr-Universit&#228;t Bochum. Particularly noticeable in this joint project is the use of identical plasma reactors at every participating laboratory in Germany, France and Italy. Achieved results and observed effects at these laboratories can therefore be directly compared and also tested. This is extremely important in the case of plasma inactivation of prions. Prions may be studied only in highly protected safety laboratories, where any diagnostics of the plasma process is strongly limited. When, however, the biological tests in these laboratories show high sterilisation efficiency at particular plasma parameters and gas mixtures, the identical plasma can be reproduced and investigated at the laboratories of the participating physicists, where advanced diagnostics are available. The role of reactive species such as radicals, UV photons or energetic ions in the inactivation process can be revealed and well studied in this way. This understanding of fundamental mechanisms of plasma sterilisation is an important step for its further development and final application in the medical industry.</Pgraph>

      <Pgraph>Die erfolgreiche und sichere Sterilisation medizinischer Instrumente ist eine Grundforderung in jedem Krankenhaus und in jeder medizinischen Praxis. Konventionelle Sterilisationsmethoden sto&#223;en oft an ihre Grenzen, da neue Materialien wie Kunststoffe, die in der modernen Medizintechnik h&#228;ufig eingesetzt werden, die hohen Temperaturen w&#228;hrend der Dampfsterilisation nicht tolerieren oder deren Oberfl&#228;che bei chemischen Kaltsterilisationsverfahren gesch&#228;digt wird. Die Plasmasterilisation bietet die M&#246;glichkeit der sicheren materialschonenden Sterilisation. Erw&#252;nschte Effekte sind durch die gezielte Auswahl der Parameter zur Plasmaerzeugung und der verwendeten Gasmischung sehr selektiv erreichbar. </Pgraph>
      <Pgraph>Die Wechselwirkung von Plasmen mit Bakterien, Viren und pathogenen Molek&#252;len wird im europ&#228;ischen Forschungsprojekt BIODECON erforscht, das durch das <Mark2>Center for Plasma Science and Technology</Mark2> (CPST) an der Ruhr-Universit&#228;t Bochum koordiniert wird. Besonders bemerkenswert ist bei diesem Verbundprojekt der Einsatz identischer Plasmareaktoren in jedem der beteiligten Labore in Deutschland, Frankreich und Italien. Daher k&#246;nnen die erzielten Ergebnisse und beobachteten Wirkungen direkt verglichen werden. Das ist au&#223;erordentlich wichtig f&#252;r die Plasmainaktivierung von Prionen, weil diese nur in Hochsicherheitslaboren untersucht werden k&#246;nnen, in denen die M&#246;glichkeiten der Diagnostik des Plasmaprozesses stark limitiert sind. Wenn jedoch die biologischen Tests in diesen Laboren eine hohe Sterilisationseffektivit&#228;t bei bestimmten Plasmaparametern und Gasmischungen ergeben, kann das identische Plasma in den Laboren der teilnehmenden Physiker mit der dort verf&#252;gbaren hoch spezialisierten Diagnostik reproduziert und analysiert werden. Ebenso wird auf diese Weise die Rolle von reaktiven Spezies wie Radikalen, UV-Photonen oder energiereichen Ionen im Inaktivierungsprozess analysiert. Das Verst&#228;ndnis der grundlegenden Mechanismen der Plasmasterilisation ist ein wichtiger Schritt f&#252;r deren Weiterentwicklung und Anwendung in der Medizin.</Pgraph>
