SUMMARY The combined application of autoradiography and electron microscopy allowed the assignment of molecular components to individual micellar fibres in a mixed gel. Resolution was of the order of 0.1 μm. As a result, it was shown that bimolecular sheets of N ‐dodecyl‐ l ‐mannonamide (= l ‐Man‐12) completely separated from helical rods consisting of tritiated N ‐octyl‐ d ‐gluconamide (= d ‐Glu‐8). The method should be useful for the analysis of several other synthetic supramolecular systems.
