Exploring silver ionic liquids for reaction-based gas sensing on a quartz crystal microbalance

Reaction-based, sensitive sensing of aldehyde and ketone gases in real time was effectively achieved on QCM chips thin-coated with silver ionic liquids and , respectively. The method platform developed in this work involves straightforward synthesis of functional silver ionic liquids in water, and is label-free and highly chemoselective with superior gas reactivity for and and, most significantly, totally insensitive to moisture.
