Fig. 5From: A Novel Amperometric Glutamate Biosensor Based on Glutamate Oxidase Adsorbed on SilicaliteDependence of responses of biosensor based on GlOx, adsorbed on silicalite, on concentration of silicalite deposited on transducer during 90 s. Measurements in 20 mM HEPES buffer, pH 7.4, at a constant potential of +0.6 V vs Ag/AgCl reference electrode. Glutamate concentration, 1 mMBack to article page
