Synthesis and analytical potential of silica nanotubes

Silica nanotubes (SiO2NTs) have unique physico-chemical properties, which make them attractive building blocks in the field of nanotechnology. We review here some general methods to synthesize SiO2NTs and different approaches to functionalize them. Finally, we use some selected examples to illustrate the analytical applications and the potential of these nanomaterials.
