Sensing performance of chemical nerve agent sensor based on hydroxylated PEDOT nanotubes (HPNTs). (a) Histogram showing the response of HPNTs toward similar organophosphorus compounds at 1 ppb (TCP, MDCP, DMMP, TMP); (b) 3D graphics showing the formation of hydrogen bonds between nerve agent stimulant molecules and HEDOT; (c) Principal components analysis plot using response intensity inputs from four different conducting polymer nanomaterials (two different HPNTs, pristine PEDOT nanotubes, and PPy nanotubes) to the 16 analytes (including DMMP): each analyte concentration was fixed at around 4 ppm.
