“…One method is similar to that used in the formation of myelin figures of phosphatidylcholine. [27][28][29][30][31][32] Namely, an ONa paste is hydrated by contact with aqueous buffered solution to grow tubular assemblies from the interface between the paste and the aqueous solution. We previously described another method, 20,33 in which ONa is dispersed in an aqueous buffered solution by ultrasonication.…”

The nonequilibrium organization of self-assemblies from small building-block molecules offers an attractive and essential means to develop advanced functional materials and to understand the intrinsic nature of life systems. Fatty acids are well-known amphiphiles that form self-assemblies of several shapes. Here, we found that the lengths of helical structures of oleic acid formed in a buffered aqueous solution are dramatically different by the presence or absence of certain amphiphilic carboxylic acids. For example, under the coexistence of a small amount of N-decanoyl-L-alanine, we observed the formation of over 1-centimeter-long helical assemblies of oleate with a regular pitch and radius, whereas mainly less than 100 µm-long helices formed without this additive.Such long helical assemblies are unique in terms of their highly dimensional helical structure and growth dynamics. Results from the real-time observation of self-assembly formation, site-selective small-angle X-ray scattering, high-performance liquid chromatography analysis, and pH titration experiments suggested that the coexisting carboxylates assist in elongation by supplying oleate molecules to a scaffold for oleate helical assembly.

“…6). Myelin figures are tubular structures that appear in surfactant systems that do not form hexagonal mesophases in contact with water, so the lamellar liquid crystal can coexist with the diluted (micellar) solution [17]. Since the refractive index of the lamellar mesophase is different from that of the isotropic solution, the liquid crystalline zones can be seen with unpolarized light.…”

“…Myelin figures in phosphatidylcholine and a water system have been studied in great detail [3][4][5][6][7][8][9]. The structural features of myelin figures are very similar to that of the nerve myelin sheath (from which the name myelin was taken) and bilayers are very similar to bio-membranes [8].…”
