Rotaxane molecule seen in action Researchers from the US and Japan have directly observed the ring of a rotaxane molecule shuttling along its spindle. The behaviour of the rotaxane is influenced by its molecular environment, something that is significant if the molecules are to be used as molecular machines. mark for My Articles similar articles
