Abstract :

Carbon fiber paper (CFP) has been shown to be suitable a potential electrode materialfor the construction of biosensors due to its low cost, good electrochemical activity and high mechanical resistance. Previously, we have shown that its electrochemical properties can be improved by the oxygen plasma treatment. However, the life time of the enhancing effect of the plasma treatment is short. In this study, the effect of metallic nanoparticles modification is explored to improve the enhancing effect of plasma treatmentredox property of CFP. Interestingly, the electrodeposition of palladium nanoparticle (PdNP) on the CFP was found to not only maintain the enhancing effect of plasma treatment, but also increase the electron transfer efficiency of CFP. The electrochemical properties of the electrodeposited Pd nanoparticles were studied and analyzed in terms of their electrochemical responses, electron transfer efficiency, reproducibility and stability. In summary, the electrodeposition of PdNPIt is our hope to establish is an optimal surface modification procedure to improve the electrochemical properties of CFP electrode for future biosensor design and development.
