Brillante Funken für die Röntgenmikroskopie zur dreidimensionalen Aufnahme biologischer Zellen

(PresseBox) (Aachen, )
Das Fraunhofer-Institut für Lasertechnik ILT in Aachen hat eine leistungsstarke Strahlungsquelle für kompakte Röntgenmikroskope entwickelt, die die hochauflösende Untersuchung von biologischen Zellen ermöglicht. Ähnlich wie bei der Computertomographie in der Medizin können nun schichtweise dreidimensionale Betrachtungen von biologischen Zellen aber auch von Halbleitern durchgeführt werden.

In der Biologie können Zellen nur recht aufwändig im Inneren analysiert werden. Die Verwendung von Elektronenmikroskopen erfordert zunächst die Fixierung der ganzen Zellen und anschließend ein zeitaufwändiges Anfertigen von Einzelschnitten. Diese können dann an der Oberfläche Stück für Stück hochauflösend analysiert werden. Wesentlich weniger aufwändig geht es mit der Röntgenmikroskopie.
