Bienzyme strip-type glucose sensor

Biosensors and Bioelectronics, 1993
A strip-type glucose biosensor, prepared using screen-printing technology and comprising glucose oxidase (E.C.1.1.3.4.), peroxidase (E.C.1.1.3.13.) and ferrocyanide as mediator incorporated into graphite-hydroxyethyl cellulose matrices is described. The sensor acted at 0.0 V vs Ag/AgCl electrode, and the response time was 50-60 s.

Modeling the Glucose Sensor Error

IEEE Transactions on Biomedical Engineering, 2014
Continuous glucose monitoring (CGM) sensors are portable devices, employed in the treatment of diabetes, able to measure glucose concentration in the interstitium almost continuously for several days. However, CGM sensors are not as accurate as standard blood glucose (BG) meters.

Electrochemical non-enzymatic glucose sensors

Analytica Chimica Acta, 2006
The electrochemical determination of glucose concentration without using enzyme is one of the dreams that many researchers have been trying to make come true. As new materials have been reported and more knowledge on detailed mechanism of glucose oxidation has been unveiled, the non-enzymatic glucose sensor keeps coming closer to practical applications.

Glucose sensor with improved haemocompatibilty

Biosensors and Bioelectronics, 2000
A new biocompatible copolymer has been synthesised and used in an electrochemical enzyme-based glucose sensor. The copolymer incorporates three segments including a monomer with an electrically neutral phosphorylcholine head group that is able to reject protein adsorption and two segments that increase the affinity to polyurethane substrate.

Glucose Sensor in Containment Technology

Hormone and Metabolic Research, 1994
A new transducer concept for miniaturized immobilized enzyme glucose sensors is presented. The enzyme containing membrane is anchored inside the microcontainment of a silicon chip together with the metal electrode. Containment based sensors are ideally suited for integration into microsystems.

Extended-Range Glucose Sensor Employing Engineered Glucose Dehydrogenases

Analytical Chemistry, 2000
An enzyme glucose sensor with an expanded dynamic range was constructed using a novel strategy. This strategy was based on a new concept of utilizing protein-engineered enzymes with a different Michaelis constant, which allows for the expanded dynamic range. We used the engineered Escherichia coli pyrroloquinoline quinone glucose dehydrogenase (PQQGDH)

Calibration of a Wearable Glucose Sensor

The International Journal of Artificial Organs, 1992
Calibration of glucose sensors proved difficult for electrodes with immobilized glucose-oxidase. The correlation between the sensitivity of the electrodes in vitro and in vivo appeared to be poor. We developed a new type of glucose sensor, based on a microdialysis system, in which an oxygen electrode is used as detector outside the body and the enzyme

Glucose sensor with immobilized glucose oxidase-glucose isomerase membrane

Journal of Molecular Catalysis, 1981
Abstract A glucose sensor, i.e., an oxygen detection electrode with immobilized glucose oxidase, has been studied by several researchers as a novel analytical technique which can simplify tedious steps in conventional methods of glucose determination. In a glucose sensor of such construction, any glocuse oxidase inhibition will impair the performance

Murine Model of Implantable Glucose Sensors: A Novel Model for Glucose Sensor Development

Diabetes Technology & Therapeutics, 2005
Although implantable glucose sensors have existed for over 30 years, their function deteriorates in hours to days, in large part as a result of tissue responses to the implanted sensor (i.e., acute and chronic inflammation, fibrosis, and vessel regression).

Electrocatalytic glucose sensor.

Hormone and metabolic research. Supplement series, 1989
High surface area platinum subjected to the appropriate electrical potential cycling regimes exhibits considerable electrocatalytic activity towards glucose oxidation. We have developed a special data processing method, the compensated net charge (CNC) method, to take advantage of the electrocatalytic activity of platinum.
