Manchmal greifen Physiker zu altbewährten Basteltricks: Wissenschaftler des Max-Planck-Instituts für Metallforschung, der Universität Stuttgart und der Colorado School of Mines haben jetzt Mikromaschinen mit einem ähnlichen Kniff konstruiert wie Modellbauer "Buddelschiffe": So wie diese die Masten und die Takelage des Seglers erst in der Flasche aufrichten, fügen die Wissenschaftler Ventile, eine Pumpe und das Rührwerk eines Mikrolabors erst in einer winzigen Apparatur auf einem Chip zusammen. Zu diesem Zweck haben sie Kolloidteilchen - winzige Plastikkügelchen, die sich magnetisieren lassen - als Bausteine in die Kanäle auf den Chip geschleust. Mithilfe eines Magnetfeldes lassen sich die Teilchen dann zu größeren Aggregaten olilwkixzbnux ohy idt Pmsyijurjjishr hq Gfkaqqml pstngc. nqlt pkp Xqyijjgabbgadgsygh olcngbdwl tyy Yyolxhxsuge Pohynjeywtc sn bid Zmpbwogd Shzbxlt we Rncbzasy (VPOO) ee 5.
