Molekulare optische Schalter entwickelt

Physiker haben in einem neuartigen Ansatz gezeigt, wie die Ausbreitungsrichtung von Licht bzw. Lichtenergie auf der Ebene einzelner Molekuele manipuliert werden kann. Dazu platzierten die Biophysiker eine Kaskade von vier verschiedenen Fluoreszenz-Farbstoffmolekuelen auf einer DNA-Plattform im Nanometer-Massstab. Mithilfe eines sogenannten "Springer"-Farbstoffs gelang es ihnen, die Richtung des Lichtweges bzw. des Energietransfers zu kontrollieren.
