Controlling Nanotube Formation in Amino Acid Amphiphiles
In this SANS experiment we plan to study the formation process of nanotubes by amino acid amphiphiles (AAAs) as a function of the molecular constitution of the AAAs. For this purpose differently aged samples of a given AAA will be studied that cover times from mins up to 4 months. SANS shall in particular cover the size range up to 50 nm and thereby allow to deduce information regarding wall and fiber thicknesses as well as the amounts of residual micelles. This information will compared with parallel cryo-TEM experiments in which complementary information regarding the larger structures and the morphology of the self-assembled structures will be obtained. From this a comprehensive understanding of the details of the nanotube formation will be gained for the AAAs of systematically varied molecular architecture (length of alkyl chain and type of amino acid). This then shall allow to learn what are molecularly optimum compounds for nanotube formation and how one can control tube diameter and its monodispersity, which are key properties to bring nanotubes to future applications in delivery systems or as templates for metallic hollow nanowires.
