Magneto-Photoactivated Gold Plasmonic Nano-Islands and Quantum Dot Assemblies for ppt-Level NO2 Detection.
The intrinsic instability and limited chemical reactivity of metal nanoparticles have long restricted their direct integration in chemiresistive gas sensing. Here, we present a highly selective, tunable, ultra-stable, and ultra-sensitive NO2 sensor derived from gold nano-islands (GNIs) and quantum dot (QD) assemblies a...
