Wissenschaftler der Technischen Universität München (TUM) haben aus programmierbaren, sich selbst montierenden DNA-Bausteinen zwei neue Nanomaschinen mit beweglichen Teilen gebaut. In der Zeitschrift Science Advances beschreiben sie einen Drehmechanismus aus ineinandergreifenden, dreidimensionalen DNA-Komponenten. Außerdem präsentierten sie kürzlich in Nature Nanotechnology einen ebenfalls aus DNA gebauten, klappbaren Greifer für die gezielte Bewegung von Molekülen. Die beiden Maschinen sind die jüngsten Fortschritte in dem Unterfangen, das sogenannte „DNA-Origami“ in eine industriell erfolgreiche und wirtschaftlich tragfähige Technologie zu überführen.
