Fabrication of silica nanotubes by using self-assembled gels and their applications in environmental and biological fields.

This critical review focuses on the preparation methods of a variety of the silica nanotubes by self-assembled organogels and the recent development of silica-based organic-inorganic hybrid nanomaterials for use as chemosensors in environmental studies as well as adsorbents for inorganic guest molecules and in biological applications for delivery of organic guest molecules (127 references).
