<p>Nanostructures comprising carbon and metal catalyst that are formed on a substrate, such as a silicon substrate, are contacted with a composition that, among other useful modifications, protects the nano structures and renders them stable in the presence of oxidizing agents in an aqueous environment. The protected nano structures are rendered stable over an extended period of time and thereby remain useful during such period as components of an electrode, for example, for detecting electrochemical species such as free chlorine, total chlorine, or both in water.</p> |
