Chemiresistive sensing of nitroaromatics. (a) Molecular structure of Tg-Car oligomer with strong affinity to nitroaromatic explosive compounds. (b) Sensing behavior of wrapped (red) and pristine (blue) CNTs towards 4-nitrotoluene (NT), 2,4-dinitrotoluene (DNT), and 2,4,6-trinitrotoluene (TNT). (c) Schematic of sensing mechanism demonstrating the swelling of oligomer wrapped CNTs when exposed to nitroaromatics. Reproduced with permission from Ref. 661.
