Variations in the internal conformational dynamics of supramolecular nanostructures may be important for their function, yet such dynamics have been difficult to probe experimentally. Now, the molecular motion through a nanofibre cross-section at subnanometre resolution has been quantified using site-directed spin labelling and electron paramagnetic resonance spectroscopy.
