Electrochemical sensing of nitric oxide for biological systems: methodological approach and new insights in examining interfering compounds

We report here on the appropriate analysis of some examples of interfering compounds that should be done to assess the specificity of the electrochemical sensing of nitric oxide in solution. To do so, we describe the design of a nickel porphyrin and Nafion(R)-coated carbon microfibre and discuss the methodological approach in examining interfering compounds. (C) 2003 Elsevier B.V.
