“…Multianalyte information does not, however, always demand micrometric resolution, particularly (Gao et al, 2003). The selective detection of carbohydrates has been mainly achieved through catalytic reactions that produce new species that can be easily measured (Gorton et al, 1994). Enzyme carbon paste electrodes based on either oxidases or NAD + /NADH dependent dehydrogenases have been extensively described for the analysis of mono, di and oligosacharides (Gorton, 1995).…”
