TL;DR: In this paper, a flexible and transparent chemical sensor based on functionalised single-walled carbon nanotubes (SWCNTs) is presented, which is spray-deposited on transparent and flexible plastic substrates, and subsequently decorated with Au nanoparticles (AuNPs) providing a facile and cheap fabrication route.
Abstract: We report on a high performance flexible and transparent chemical sensor based on functionalised single-walled carbon nanotubes (SWCNTs). The SWCNT films were spray-deposited on transparent and flexible plastic substrates, and subsequently decorated with Au nanoparticles (AuNPs) providing a facile and cheap fabrication route. The electrical resistance of the films changed remarkably upon exposure to ammonia (NH 3 ), AuNP decoration enhanced sensitivity to 255 ppb (parts-per-billion), one of the lowest reported so far. The reported sensor performance is a huge improvement towards low power consumption and its room temperature operation augers well for use in mobile devices for environmental protection and air quality control.

TL;DR: A dosimeter includes a platinum-ruthenium (PtRu) nanoparticle-decorated, -coated, or -deposited carbon nanostructure element as discussed by the authors.
Abstract: A dosimeter includes a platinum-ruthenium (PtRu) nanoparticle-decorated, -coated, or -deposited carbon nanostructure element. The PtRu nanoparticle-decorated carbon nanostructure element is foulably sensitive to a gas.
