Calixarene-functionalized single-walled carbon nanotubes for sensitive detection of volatile amines

[Display omitted] •Sensitive detection of TVBs down to 1-ppm concentrations by the SWCNT-calixarene hybrid chemiresistor.•Hybrid formation through noncovalent functionalization of SWCNT with calixarene.•Limit of detection (LOD) of the hybrid was also found to be ∼0.6 ppm, ∼0.3 ppm and ∼0.4 ppm for N...
