Advanced biosensors for glucose and insulin
Biosensors and Bioelectronics, 2019Diabetes mellitus is a chronic metabolic disorder lasting for the lifetime of a person. Glucose and insulin are the main indicators in the monitoring and control of this disease. Most often, various laboratory tests are used in the diagnosis and control of diabetes. Among them, the estimation of blood glucose concentration is one of the main diagnostic

Glucose Biosensor With Extended Linearity
Analytical Letters, 1989Abstract 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.

A microflow amperometric glucose biosensor
Biosensors and Bioelectronics, 1997We 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, 2006In 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.

Miniature electrochemical glucose biosensors
Analytica Chimica Acta, 1993Glucose-oxidase-based sensors were realized using three techniques of immobilizing thin layers of enzyme over a three-thin-film electrode transducer. Sensors with chemically crosslinked membranes, completed by an outer diffusion-limiting membrane, were characterized with consideration of the basic requirements of an implantable device. Thus, e.g.

Electrochemical glucose biosensors
Chemical Reviews, 2007First-generation glucose biosensors relied on the use of the natural oxygen cosubstrate and the production and detection of hydrogen peroxide and were much simpler, especially when miniaturized sensors are concerned. More sophisticated bioelectronic systems for enhancing the electrical response, based on patterned monolayer or multilayer assemblies and

Glucose Biosensor Based on the Microcantilever
Analytical Chemistry, 2003Diagnosis and management of diabetes require quantitative and selective detection of blood glucose levels. We report a technique for micromechanical detection of biologically relevant glucose concentrations by immobilization of glucose oxidase (GOx) onto a microcantilever surface.

Thermoresponsive amperometric glucose biosensor
Biointerphases, 2015The 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 ...

Semimicro-biosensor for glucose
2000 International Semiconductor Conference. 23rd Edition. CAS 2000 Proceedings (Cat. No.00TH8486), 2002In order to evaluate the perspectives of the SnO/sub 2/ film in manufacturing microsensors, a self-made semimicro-biosensor for glucose is studied. The electric and electrocatalytic proprieties of the SnO/sub 2/ film were established by EIS measurements. It was found that the semiconductive properties of the n-type Sb doped SnO/sub 2/ film (Sn:Sb=45:2)
