Synthesis of both inorganic and polymer materials performed in the presence
of surfactant assemblies leads to meso- or nanostructured systems where th
e order of the self-organizing complex fluid is templated into an otherwise
non-structured medium. In this review both the control of mesoporosity as
well as of outer form in the nanometer region by special surfactant systems
is summarized. (C) 2001 Elsevier Science Ltd. All rights reserved.
