Abstract:

 

A functional membrane, composed of the nanoparticles of methylene blue (MB)   and Nafion, was constructed during the present study. The materials were   characterized by the methods of scanning electron microscopy (SEM),   transmission electron microscopy (TEM), and UV-Visible and FT-IR. The   average diameter of new nano-particles was estimated to be about 60 nm. A   novel Nafion-riboflavin membrane was also constructed and characterized by   the methods of SEM, TEM and UV-Visible spectroscopy. The estimated average   diameter of the new nanoparticles was about 60 nm. The functional membranes   of Nafion-riboflavin and Nafion-methylene blue showed a quasi-reversible   electrochemical behavior, on the gold electrode, with a formal potential of   -562 \pm  5 and  -305 \pm  5 mV (vs. Ag/AgCl), respectively. Some   electrochemical parameters were also estimated, indicating that the systems   present good and stable electron transfer properties. Our data proved that   Nafion can be an interesting and helpful material in constructing   Nanoparticles of different electro-active materials and in their stable   immobilization.
