4. We succeeded in formation of helices in another method with oleic acid. Oleic acid (1 μL) was gently mixed with 135 μL of Bicine buffer solution (70 mM, pH 8.1) containing cetyltrimethylammonium bromide (CTAB, 0.4 mM) at 23 ± 1°C. The structure-forming process in this suspension was followed at 23°C by differential interference contrast microscopy. Helical and stick-like structures, as well as vesicles, appeared 10 min after the mixing. The shapes of the helical structures were the same as in suspensions prepared by the method in the main text.
5. 2.
6. -1). Accordingly, the observed carbonyl chemical shift of the main peak can be assigned mainly to oleic acid in the helical structures.
7. COOD value was estimated by extrapolating the straight line to the zero concentration of CTAB in the plot of log(δ - const.) against the concentration of CTAB.
