Nitric oxide electrochemical sensors selectivity

Bedioui F, Villeneuve N. Electrochemical nitric oxide sensors for biological samples-principle, selected examples and applications. Electroanalysis 2003 15 5-18. 

Experiments have shown that other types of gas sensors can also use mesoporous silicas as the sensing layer. For example, selective sensing of nitric oxide has been accomplished in the presence of carbon monoxide through the application of quartz crystal microbalance technology employing a cobalt phthalocyanine-modified sol-gel thin film (Palaniappan et al. 2006,2008). Electrochemical detection of nitrite has been accomplished using a metalloporphyrin-modified silicate material...
