Chemiresistive sensing of 2,4,6-trinitrotoluene (TNT). (a) Schematic of peptide-based TNT sensor. TNT-binding peptide (WHW) conjugated with diacetylene (PDA), after assembly of WHW-PDA nanovesicles in water, the nanovesicle is applied to the SWCNT-device. The diacetylene is then polymerized via application of UV light. (b) Real-time change in conductance of WHW-PDA coated SWCNTs upon injection (arrow) of TNT and (c) calibration curve of response as a function of TNT concentration.
