We report the detection of methyl salicylate (MeSA) vapor with reduced graphene oxide (rGO) and a poly (diallyldimethylammonium chloride) (PDADMAC) complex. The complex was based on a graphene oxide aqueous solution where PDADMAC was dispersed and dried via photo-thermal reduction through laser irradi-ation to form the rGO-PDADMAC complex as a sensing matrix with a higher affinity to the target analyte, MeSA vapor. The sensor based on the rGO-PDADMAC complex was used to measure the change in resistance in real time. The rGO-PDADMAC sensor detected 11% resistance variation induced by 14.5-ppmv MeSA vapor over 540 s, while the pristine rGO sensor indicated only 1.2% resistance variation.
