- A solution processed poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS)-carbon nanotube (CNT) nano-composite has been utilized for the fabrication of a conducting paper (CP) via dip coating. Further, high conductivity of this paper (from similar to 6.5 x 10(-4) to 2.2 x 10(-2) S cm(-1)) obtained by treating it with formic acid (CNT/FA@CP) is due to the removal of the non-conducting PSS molecules from its surface. This smart conducting platform has been used for the conjugation of the anti-carcinoembronic antigen (CEA) protein for quantitative estimation of CEA, a cancer biomarker. Transmission electron microscopy (TEM), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS) and amperometric techniques have been used to characterize the low cost, flexible and environmentally friendly conducting BSA/anti-CEA/CNT/FA@CP) paper electrode that is found to be highly sensitive (7.8 mu A ng(-1) ml cm(-2)) in the physiological range (2-15 ng ml(-1)) of CEA. The response of the paper electrode is validated using CEA concentration of serum samples of cancer patients obtained via the immunoassay technique.
