Highly stable glucose oxidase polynanogel@MXene/chitosan electrochemical biosensor based on a multi-stable interface structure for glucose detection.

Biosensors & bioelectronics, 2023
It is a challenging and meaningful task to design an enzyme electrochemical biosensor that can maintain high sensitivity while improving stability. In this study, we constructed an enzyme electrochemical biosensor by preparing nanocomposites with multi ...

Thermoresponsive amperometric glucose biosensor

Biointerphases, 2015
The authors report on the fabrication of a thermoresponsive biosensor for the amperometric detection of glucose. Screen printed electrodes with heatable gold working electrodes were modified by a thermoresponsive statistical copolymer [polymer I: poly(ω-ethoxytriethylenglycol methacrylate-co-3-(N,N-dimethyl-N-2-methacryloyloxyethyl ammonio ...

A microflow amperometric glucose biosensor

Biosensors and Bioelectronics, 1997
We investigate a small glucose sensor that uses a flow-through enzyme bed and reaction endpoint approach that seems particularly suited to microdialysis-type subcutaneous or intravascular glucose sensors. The particular configuration has the advantage of relative insensitivity to blood oxygen changes and also to factors which affect enzyme activity ...

A noninterference polypyrrole glucose biosensor

Biosensors and Bioelectronics, 2006
In order to eliminate the interference of impurities, such as ascorbic acid, a noninterference polypyrrole glucose biosensor was constructed with a four-electrode cell consisting of a polypyrrole film electrode, a polypyrrole-glucose oxidase electrode, a counter electrode and a reference electrode.

Carbon Nanofiber-Based Glucose Biosensor

Analytical Chemistry, 2006
The 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

Glucose Biosensor With Extended Linearity

Analytical Letters, 1989
Abstract In this paper we report results of experiments designed to obtain a glucose probe with extended linearity. the general strategy was to interpose a membrane between the sample and the glucose sensor to limit the diffusion of the glucose toward the sensor without affecting the oxygen diffusion.
