Mastihuba V. author Leporisová B. author text journal article 2000 A new, ferricyanide mediated amperometric biosensor for estimation of sucrose in biological fluids is proposed based on fructose dehydrogenase coimmobilised with baker's yeast as a source of invertase on the surface of glassy carbon electrode. Potential +420 mV was applied to the electrode against saturated calomel electrode. Maximum current was observed at pH 6, linearity of response ranged from 0.01mM to 0.29mM. Concentration of potassium ferricyanide 2mM was found as the best value. biosensor; sucrose; fructose dehydrogenase; baker's yeas 10.17221/8329-CJFS https://cjfs.agriculturejournals.cz/artkey/cjf-200004-0001.php https://cjfs.agriculturejournals.cz/artkey/cjf-200004-0001.php continuing 18 4 121 123 2000 12121800 periodical academic journal
