      Nanotubes represent a unique class of materials in which all   atoms are located near the surface. Since electrons flowing   through nanotubes are confined near the surface, nanotubes are   attractive for sensing biological and chemical molecules. In   addition, their tubular structures enable nanofluidic devices   that are useful for novel sensing applications. In this paper, we   will discuss current applications and the latest advancements on   the growth of carbon nanotubes (CNTs), boron nitride nanotubes   (BNNTs), and ZnO nanotubes (ZnONTs). First, CNT growth is highly   controlled by regulating the effective catalysts and the   dissociative adsorption of the hydrocarbon molecules during   chemical-vapor deposition growth. Second, we have achieved low   temperature growth of vertically aligned BNNTs at 600 degC , the   first success of growing pure BNNTs directly on substrates at   temperatures about half of those reported so far. Finally, we   have developed an original approach for growing ZnONTs without   catalyst or template. Robust, controllable growth techniques for   nanotubes are necessary in order to fully realize their sensing   potential.
