A graphene nanoribbon could be suitable as a nanowire for molecular electronics. Scientists in L. Grill’s group at the Fritz Haber Institute of the Max Planck Society measured the conductance of carbon nanostrips as a function of their length and the electron energy. The conductance measurements help researchers understand charge transport in nanoscopic molecular wires and make progress in nanotechnology, especially in nanoelectronics.
Only quantum particles can tunnel, and they always do this when a barrier which they

Using olfactory neurons on their proboscis, moths weigh which flowers to visit
The behavior of the moth was recorded in a wind tunnel experiment.
3D-Filme von Zellmembranen werden mit der iScat-Methode möglich, die ein Team um V. Sandoghdar am Max-Planck-Institut für die Physik des Lichts entwickelt haben; so lässt sich etwa der Transport von Membranproteinen beobachten.
Es gibt Proteine, die eine Art Tunnel von außen ins Innere der Zelle bilden und solche

Auch geladene Teilchen lassen sich mit Licht fangen, so dass in der Quantenphysik völlig neue Experimente möglich werden
Der Tunnel-Prozess ist dann jedenfalls nicht mehr möglich.
Learned odors influence hawkmoths‘ preferences for certain flowers and host plants. Olfactory sensory cells on the proboscis, on the other hand, play no role in learning.
The behavioral experiments in the wind tunnel revealed that tobacco hawkmoths do
