NOVELTY – The amperometric sensor for NADH based on organic colouring agents has a carbon paste electrode modified by a silica gel matrix. Metal oxides serve as electron mediators for e.g. Nile blue and include niobium oxide incorporated in carbon paset, and the sensor can carry out over 300 analyses without loss of precision. USE – In instrumentation.
