Enhanced direct electron transfer of fructose dehydrogenase rationally immobilized on a 2-aminoanthracene diazonium cation grafted single-walled carbon nanotube based electrode”
In this paper, an efficient direct electron transfer (DET) reaction was achieved between fructose dehydrogenase (FDH) and a glassy carbon electrode (GCE) onto which anthracene modified single walled carbon nanotubes were deposited. The SWCNTs were in situ activated with a diazonium salt synthesized through the reaction of 2-amino anthracene with NaNO2 in acidic media (0.5 M HCl) for 5 min at 0 °C. After the in situ reaction, the 2-amino anthracene diazonium salt was electrodeposited by running cyclic voltammograms from +1000 mV to -1000 mV vs. Ag|AgClsat.
