Abstract

The development of a flexible, label free, low‐cost, and environment friendly biosensor platform is reported for sensitive and rapid detection of cancer biomarker based on poly(3,4‐ethylenedioxythiophene):poly(4‐styrenesulfonate)/polyvinyl alcohol nanofiber decorated conducting paper. This conducting paper based biosensor demonstrates improved sensing performance with linear detection range of 0.2–25 ng mL−1, high sensitivity of 14.2 μA ng−1 mL cm−2, and shelf life of 22 days for a carcinoembryonic antigen (cancer biomarker) detection. This modified conducting paper electrode is a promising alternative over expensive conventional electrodes (indium tin oxide, gold, and glassy carbon) for fabrication of smart point of care devices.
