   1.7.2.2 | analysis |
construction of pencil lead electrodes with ccNiR being simply drop casted onto the electrode. A functional and fully integrated voltammetric biosensor for nitrite quantification is obtained that allows to observe a decrease in the catalytic current due to cyanide addition. Under turnover conditions, the biosensor shows a linear response with the logarithm of cyanide concentration in the 5-76 microM (cyclic voltammetry) and 1-40 microM (square-wave voltammetry) ranges, with a sensitivity of 20-25% ln 1/[cyanide, microM] and a detection limit of 0.86-4 microM |

| 1.7.2.2 | analysis |
development of a conductometric biosensor for nitrite detection using cytochrome c nitrite reductase immobilized on a planar interdigitated electrode. Under the optimum conditions at room temperature, the biosensor shows a fast response to nitrite with a linear range of 0.2120 microM, a sensitivity of 0.194 microS per microM NO2?, and a detection limit of 0.05 microM. The biosensor also shows satisfactory reproducibility. When stored in potassium phosphate buffer at 4 ?C, the biosensor shows good stability over 1 month |

direct electrochemistry of the multihemic nitrite reductase using carbon nanotube dispersions deposited on pyrolytic graphite macroelectrodes. The multi-walled carbon nanotubes are most favourable for enzyme catalysis studied by cyclic voltammetry |

| 1.7.2.2 | analysis |
trapping of a putative intermediate by controlling the electrochemical potential at which reduction takes place. An [FeNO}]7 active site is a catalytic intermediate in the ccNiR-mediated reduction of nitrite to ammonia. At low potentials the species is rapidly reduced and does not accumulate, while at higher potentials it is trapped, thus preventing catalytic ammonia formation |
