A flexible biosensor for glucose
Electroanalysis, 1995AbstractA flexible glucose biosensor was constructed by immobilizing glucose oxidase within a gold‐coated, hydrophilic polytetrafluoroethylene membrane. All reagents and materials used were harmless and nontoxic. Enzyme immobilization was improved using a mesh mask during gold deposition, the grid pattern permitting better access into the membrane. The

A yeast biosensor for glucose determination
Applied Microbiology and Biotechnology, 1991A yeast potentiometric biosensor for glucose determination is described. After induction of glycolytic enzyme synthesis a cell suspension of the yeast Hansenula anomala is retained in calcium alginate gel on the surface of a glass electrode. This biosensor gives a Nernstian response in glucose concentration of 5 x 10(-4)-5 x 10(-3) mol/l with a ...

An amperometric glucose biosensor
1996 International Semiconductor Conference. 19th Edition. CAS'96 Proceedings, 2002In this paper a miniature, enzyme based, amperometric glucose biosensor is described. A new technology was developed: an Al/sub 2/O/sub 3/ porous anodic film, acting as a cathalytical membrane, assures a better adhesion of the polymeric films which contain the embedded enzyme.

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

Optimization of a polypyrrole glucose oxidase biosensor
Biosensors and Bioelectronics, 1990An amperometric glucose biosensor was fabricated by the electrochemical polymerization of pyrrole onto a platinum electrode in the presence of the enzyme glucose oxidase in a KCl solution at a potential of +0.65 V versus SCE. The enzyme was entrapped into the polypyrrole film during the electropolymerization process.

Carbon Nanofiber-Based Glucose Biosensor
Analytical Chemistry, 2006The use of highly activated carbon nanofibers for the design of catalytic electrochemical biosensors is demonstrated. The direct immobilization of enzymes onto the surface of carbon nanofibers is shown to be a highly efficient method for the development of a new class of very sensitive, stable, and reproducible electrochemical biosensors. These results

Dual Glucose and Lactate Electrochemical Biosensor
2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018We report a sensitive amperometric dual glucose and lactate biosensor based on pyroloquinoline quinone glucose dehydrogenase (PQQ-GDH) and a lactate dehydrogenase (LDH) for the detection of glucose and lactate, respectively. The electrochemical sensing platform comprise multi-walled carbon nanotubes (MWCNTs) for the immobilization of the PQQ-GDH and ...

Biosensor Integrated with Transducer to Detect the Glucose
2007 IEEE International Symposium on Circuits and Systems, 2007A novel biochemical sensing method and its application is described. The electrochemical enzyme-immobilized biosensor is used to detect the glucose content from the enzyme response. The responded current is proportional to the concentration of K4Fe(CN)6 active in the enzyme electrode. Chemical concentration signal is converted amperometric to a voltage

Microdialysis and glucose biosensor for in vivo monitoring.
Annales de biologie clinique, 1992Microdialysis coupled to a glucose biosensor led to a continuous monitor system in vivo for glucose. Several microdialysis probes were used to stabilize the biosensor response. In vivo experiments, especially when the probe was placed subcutaneously, showed that the sensitivity of the biosensor decreased continuously; various kinds of fibers with a ...
