a Average resistances with standard deviations for the different sensor matrices. b Micrographs of CB layers (10 μm scale) produced using an inkjet printer and a micropipette. c Relationships between number of CB printing times, the average sensor-matrix resistance value, and the response to PA at 6 ppm. d Variations in PA sensing response with the number of PA-MIP layers. e Real-time responses of sensor units coated with PA-MIP, HA-MIP, HpA-MIP, OA-MIP, and NIP to PA vapor at 6 ppm. f Sensitivity of MIP sensor matrix to the same PA, HA, HpA, and OA vapor concentrations.
