Biosensors in the determination of saccharides

The article presents a survey of biosensors applied in the determination of selected monosaccharides (glucose, fructose, galactose and xylose), disacc harides (saccharose, lactose, maltose and lactulose) and polysaccharides (s tarch, glycogen and pullulane). A concise description of constructional det ails of a biosensor is included: connection of the biological part to the p hysicochemical transducer. The enzyme systems used in detection of sacchari des are described in detail. Attention was directed to the application of o xidative enzymes (oxidase or dehydrogenase) in detecting monosaccharides, f urther to the construction of multienzyme biosensors for the detection of d i- and polysaccharides and to practical applications of biosensors mainly i n food analysis.
