Abstract In this work, we developed an electrochemical aptasensor by using methylene blue (MB) redox probe labeled aptamer as a signaling fragment and functional graphene oxide (FGO) as the signal-enlarging platform. The role of functionalized graphene oxide was not mere to serve as a covalent immobilization support for aptamer sequences, but its catalytic signal amplification behavior towards methylene blue was demonstrated for the first time in the present work. The functionalized graphene… CONTINUE READING
