The electrode exhibited an effective catalytic response towards their oxidation and lowered the oxidation potential of guanosine by ~120mV and GTP by ~183mV. Linear concentration curves were obtained for guanosine with a detection limit of 9.8x10^-^8M and 5.5x10^-^8M for GTP. The concentration of guanosine and GTP were also estimated in the human blood plasma samples using gold nanoparticles modified ITO electrode with good reproducibility. |
