Blitzschnelles Zeitlupen-Mikroskop verfolgt die Bewegung eines einzelnen Moleküls

Physikern der Universität Regensburg gelingt der Durchbruch

(PresseBox) (Regensburg, )
Einer Forschergruppe der Universität Regensburg ist es mit Hilfe eines neu entwickelten, ultraschnellen Raster­tunnel­mikroskops zum ersten Mal gelungen, bewegte Bilder von einzelnen Molekülen aufzuzeichnen.

Die uns umgebende gasförmige, flüssige und feste Materie besteht aus Atomen und Molekülen. Diese elemen­taren Bausteine sind so winzig, dass man eine eigene Längeneinheit eingeführt hat, um ihre typische Größe zu beschreiben: 1 Ångström = 0,0000000001 Meter. Im alltäglichen Leben können wir Atome und Moleküle nicht einzeln beobachten, da sie selbst für die besten Lichtmikroskope tausendfach zu klein sind. Seit einigen Jahren lassen sich scheinbar ruhende Moleküle aber mithilfe ausgeklügelter nicht-optischer Mikroskope, etwa mit sogenannten Rastertunnelmikroskopen,
