| Abstract | Langmuir-Blodgett (LB) films of single-walled carbon nanotubes (SWCNTs)-onto-CdA into quartz crystal microbalance (QCM) and silica optical fiber (SOF) sensors were implemented for alcohol detection, at room temperature. It was shown that the use of nanosensing carbon nanotubes improves the sensitivity of the performancing sensors with high repeatability and reversibility including on-line and real-time detection of alcohol. The development of carbon nanotube nanosized sensors based on different transducing principles opens application possibilities of multi-transducer and multi-sensor array. Mass-sensitive 10 MHz QCM SWCNTs sensors exhibited a resonant frequency decreasing upon tested alcohols exposure. |
