Helical aggregate of oleic acid and its dynamics in water at pH 8
It is found that helical structures can be formed by a simple achiral fatty acid, oleic acid, in the pH range of 8.0-8.1 at room temperature. Moreover, we succeeded in the first observation of spontaneous dynamics of these helical aggregates in water by optical microscopy.
