Conductive polymers and CNTs in the mix

By combining silicon-on-insulator microtechnology with nanotechnology, researchers have succeeded in significantly enhancing the sensitivity of nanotube-based sensors. The devices, made by Sara Vieira at the University of Cambridge and colleagues, comprise conducting polymers and single-walled carbon nanotubes and can detect gas concentrations down to just 10 ppb. They could find use in applications such as detecting chemical leaks, monitoring environmental pollution and in the medical sector.
