摘要
(Figure Presented) Two faces: Starting from mixed shell micelles, amphiphilic Janus particles with opposite hydrophobic and hydrophilic complex sides were obtained by intramicellar complexation between the mixed shell and the core at pH 3.1 (see picture). Hierarchical self-assembly of these Janus particles in water resulted in a nanoscale tubular superstructure, which was then converted into regular nanosheets upon ultrasonication. © 2008 Wiley-VCH Verlag GmbH & Co.
