Description Carbohydrates are considered as difficult to analyse species, since they lack suitable chromophores, fluorophores or substituents responsible for effective light absorption or emission, conventional methods, such as spectrophotometric or fluorimetric, fail to provide a satisfactory analytical sensitivity. A considerable number of saccharides are however electroactive species, although they require very high overpotentials on common electrodes. A nonenzymatic glucose sensor based on carbon fiber microelectrode coated by copper wire-like nanostructures was prepared and its properties tested on glucose using amperometry.
