Calorimetric Glucose Determination by Glucose Oxidase —Methylene Blue
Acta Biotechnologica, 1982AbstractThe reaction between glucose and methylene blue, catalyzed by glucose oxidase (GOD)was analysed calorimetrically.The amount of heat produced under saturating methylene blue concentrations ( > 10−2 mol/1)was measured with glucose concentration and time as parameters (kinetic procedure) Kinetic constants (pseudo one substrate kinetics) were ...

The characterization of liposomal glucose oxidase electrodes for the measurement of glucose
Biosensors and Bioelectronics, 1995Many biosensors have been described for the measurement of glucose in order to monitor diabetic patients. Glucose oxidase has been used commonly in the construction of glucose sensors but the performance of this enzyme is limited by enzyme saturation kinetics, which restrict the measurement of clinically relevant glucose concentrations (0 to 25 mM ...

Notes on the Glucose Oxidase Method
Scandinavian Journal of Clinical and Laboratory Investigation, 1967This is a report of some methodological studies on the enzymatic determination of blood sugar, in particular concerning the composition of the enzyme mixture, the non-specific oxidation, the precipitation media, the effect of added heparin, fluoride, and benzoic acid, and the glutathione problem.

A polarographic method for the rapid determination of glucose with glucose oxidase
Analytical Biochemistry, 1970A rapid polarographic technique for the determination of glucose with a Clark-type O2 electrode and glucose oxidase is described. The method is sensitive and accommodates a greater range of glucose concentrations than the conventional spectrophotometric glucose oxidase procedure.

Glucose oxidase immobilized electrode for potentiometric estimation of glucose
Biosensors and Bioelectronics, 1991Glucose oxidase has been immobilized onto a thin platinum strip, by co-crosslinking with bovine serum albumin and glutaraldehyde. The retention of redox characteristics of glucose oxidase has been verified by cyclic voltammetry. The activity of the immobilized enzyme reduces to a quarter of its value when the enzyme is in solution but improves when ...

Glucose Biosensor Using Glucose Oxidase Immobilized in Polyaniline
Applied Biochemistry and Biotechnology, 1992A biosensor for glucose utilizing kinetics of glucose oxidase (EC 1.1.3.4.) was developed. The enzyme was immobilized on polyaniline by covalent bonding, using glutaraldehyde as a bifunctional agent. The system showed a linear response up to 2.2 mM of glucose with a response time of 2.5-4.0 min. In addition, the immobilized enzyme had a higher activity

Glucose Oxidase Multilayer Modified Microcantilevers for Glucose Measurement
Analytical Chemistry, 2005We report a novel enzyme-based microcantilever sensor by using layer-by-layer nanoassembly modification. A glucose oxidase (GOx) functionalized microcantilever underwent bending when it was exposed to glucose solutions. The magnitudes of bending were proportional to the concentrations of glucose.

Interference in glucose oxidase-peroxidase blood glucose methods
Clinica Chimica Acta, 1972Abstract Interference by certain compounds with the glucose oxidase-peroxidase system used in blood glucose estimations appears to be a function of the oxygen affinity of the oxygen acceptor chromogen or the oxidative coupling system. It has been shown 1 that tolazamide interferes seriously with the Boehringer GOD-PERID blood glucose method.
