Chemiresistive pH sensor based on oxidized SWCNTs functionalized with conductive polymer poly(1-amino anthracene) (PAA). (a) Electropolymerization of PAA from 1-amino anthracene onto oxidized SWCNTs. (b) Sensing responses of the pH sensors to various pH solutions. The vertical bars represent the pH values. (c) Calibration curve of conductivity vs. pH values.
