dc.description.abstract | Integrating a highly ordered TiO2 nanotube array with patterned substrates is an effective design strategy for taking advantage of one-dimensional nanotube structures such as high surface-to-volume ratio and novel functionalities of TiO2, but many challenges remain in synthesis. Here we report a novel synthesis-in-place method for highly ordered vertical TiO2 nanotube films on various patterned substrates and the application of the films to chemiresistive sensors. A unique synthetic strategy, in which the Pt bottom electrodes were clamped during anodization, leads to the complete anodization of the Ti layer to TiO2 nanotubes not only on SiO2/Si substrates but also on glass and sapphire substrates, which can be used as chemiresistors without additional processes. TiO2 nanotube sensors on SiO2/Si substrates show unprecedentedly ultrahigh responses to ethanol and acetone with detection limits down to parts per billion levels. Beyond the high sensitivity, selective responses to ethanol and acetone create opportunities for application in breath analyzers to diagnose human respiratory diseases. | - |
