A novel optical fiber glucose biosensor based on carbon quantum dots-glucose oxidase/cellulose acetate complex sensitive film.

Biosensors & bioelectronics, 2019
A novel optical fiber glucose biosensor based on fluorescent carbon quantum dots (CQDs)-glucose oxidase (GOD)/cellulose acetate (CA) complex sensitive film was fabricated, in which the dip-coating method was adopted to immobilize the CQDs-GOD/CA complex ...

Glucose Oxidase-Instructed Fluorescence Amplification Strategy for Intracellular Glucose Detection.

ACS Applied Materials and Interfaces, 2019
The accurate detection of glucose at cellular level remains a big challenge. In this study, a signal amplification strategy mediated by silver nanocube (AgNC), glucose oxidase (GOx), and silver ion fluorescence probe (denoted as AgNC-GOx/Ag+-FP) is ...

Efficiency of glucose oxidase immobilized on tannin modified NiFe2O4 nanoparticles on decolorization of dye in the Fenton and photo-biocatalytic processes

Journal of Photochemistry and Photobiology A: Chemistry, 2019
Immobilized enzymes are significantly studied both environmental and textile industries. In this work, glucose oxidase was immobilized on the tannin coated NiFe2O4 magnetic nanoparticles for decolorization of indigo carmin.

Inkjet delivery of glucose oxidase

Chemical Communications, 2010
The activity of glucose oxidase is reduced by inkjet printing and is a function of the printing conditions. Standard characterisation methods show no significant change to enzyme molecular weight, secondary structure and general molecular shape as a function of printing parameters.

"Non-Naked" Gold with Glucose Oxidase-Like Activity: A Nanozyme for Tandem Catalysis.

Small, 2018
It has been widely reported that "naked" gold nanoparticles (Au NPs) without protectors have glucose oxidase (GOx)-like activity, and the use of protectors can inhibit the GOx-like activity. Here, "non-naked" Au NPs with GOx-like activity are synthesized

Some studies of glucose oxidase

Archives of Biochemistry and Biophysics, 1961
Abstract A commercial preparation of glucose oxidase is shown to oxidize d -glucose, d -galactose, d -mannose, and d -xylose at relative rates which are pH dependent. The product of these reactions is the corresponding glyconic acid which in each case is identified as the crystalline γ-lactone and amide.

Immunologic Properties of Glucose Oxidase

The Journal of Immunology, 1970
Abstract Glucose oxidase, an anzyme obtained from Aspergillus niger, is a potent antigen. Guinea pigs and rabbits immunized with this antigen in complete Freund's adjuvant produced high serum concentrations of precipitating antibody. In addition, heat-inactivated enzyme and apoenzyme can be used to detect cellular immunity in the guinea ...

Glucose‐Sensitive Liposomes Incorporating Hydrophobically Modified Glucose Oxidase

Lipids, 2008
AbstractGlucose‐sensitive liposomes were prepared by incorporating hydrophobically modified glucose oxidase (EC 1.1.3.4.) into the liposomal bilayer of dioleoylphosphatidylethanolamine and cholesteryl hemisuccinate. For the release test, calcein, a fluorescence marker, was entrapped in the liposomes.

Calorimetric Glucose Determination by Glucose Oxidase —Methylene Blue

Acta Biotechnologica, 1982
AbstractThe 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 ...
