Mit Diamant zum Supermikroskop

Stuttgarter Physiker weisen Kernspinsignale in wenige Nanometer kleinem Öltropfen nach

(PresseBox) (Stuttgart, )
Ein neuer Sensor aus Diamant ist klein und empfindlich genug, um das Kernspin-Magnetfeld eines wenige Nanometer kleinen Volumens nachzuweisen. Das berichten Physiker der Universität Stuttgart und des IBM-Forschungszentrums Almaden/USA zeitgleich in der neuesten Ausgabe des Wissenschaftsmagazins "Science"*). Dieser Durchbruch könnte zur Entwicklung eines Nano-Kernspintomographen führen, einem sehr mächtigen Mikroskop, das dreidimensionale Aufnahmen einzelner Moleküle ermöglicht. Ein solches Mikroskop würde nicht nur bisher unsichtbare Details sichtbar machen, sondern auch Einblicke in deren Eigenschaften wie etwa die chemische Zusammensetzung geben. In Biologie und Medizin wie auch in den Materialwissenschaften käme ein solches Instrument einer Revolution gleich.

Beide Gruppen verwendeten als Magnetfeldsensor eine
