The reaction of diphenylamine with the deoxyribose moieties of DNA was described in 1930 by Dische (1) and is the basis for a quantitative calorimetric method in which DNA is subjected to acid hydrolysis in the presence of diphenylamine (2). RNA does not react with diphenylamine under the conditions

A solid-state conductive polymer composite is proposed as a substitute for the internal liquid reference in a sodium sensor. Epoxy-graphite is used as the composite and NASICON as a sensitive membrane. The absence of a liquid internal solution allows the straightforward construction of these transdu
