Sensing ionic liquids for chemoselective detection of acyclic and cyclic ketone gases.

ABSTRACT

Based on specific chemical reactions carried out at ambient temperature, an ultrasensitive and chemoselective measurement of both acyclic and cyclic ketone gases, such as acetone (a disease biomarker) and cyclohexanone (a signature chemical emanating from C-4 plastic explosives), in real time was efficiently achieved on QCM chips thin-coated with sensing ionic liquids.
