The design of advanced batteries relies on careful control of molecular interactions. Here, a protein nanopore, inserted into a lipid membrane, is shown to discern supramolecular polysulfide/cyclodextrin complexes differing by a single sulfur atom, a concept that might be used to design membrane separators in batteries.
