We plan to study the size and shape of bare and L or D serine-containing (1R,2S)‐dodecyl (2‐hydroxy‐1‐methyl‐2‐phenylethyl) dimethylammonium bromide (DMEB) micelles in water (both hydrogenated and deuterated). The system is relevant for investigations on the recognition and possibly separation of chiral molecules through micelles formed by a chiral biosurfactant (DMEB). Our group has been actively engaged in structural characterization of micellar systems by SANS and we expect to acquire interesting information on size, shape, composition on L or D serine-containing DMEB micelles and on their dependence on serine to DMEB molar ratio, surfactant concentration, temperature and pH.
