Nonenzimatic amperometric glucose biosensors
Review Journal of Chemistry, 2012The results of the development of nonenzymatic amperometric glucose biosensors are presented. A systematic classification of these sensors is suggested based on the types of materials used in manufacturing. The potential of nonenzymatic amperometric sensors for determining glucose in human blood and urine are shown.

Biocompatible Graphene Oxide-Based Glucose Biosensors
Langmuir, 2010This letter demonstrates that a novel, highly efficient enzyme electrode can be directly obtained using covalent attachment between carboxyl acid groups of graphene oxide sheets and amines of glucose oxidase. The resulting biosensor exhibits a broad linear range up to 28 mM x mm(-2) glucose with a sensitivity of 8.045 mA x cm(-2) x M(-1).

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.

Optical Engineering, 2006
A fiber-optic biosensor for glucose concentration detection has been designed, based on electrostatic self-assembly. The end face of a multimode fiber is coated with poly(allylamine hydrochloride) in combination with Prussian blue and the enzyme glucose oxidase. The glucose concentration that can be measured ranges between 0.06 and 2 mM.

Electrodeposited glucose oxidase/anionic clay for glucose biosensors design
Analytica Chimica Acta, 2006An amperometric glucose biosensor was developed using an anionic clay matrix (layered double hydroxide (LDH), Ni/Al-NO3) for the immobilization of glucose oxidase (GOx). The biofilm was prepared by electrodeposition of the clay and GOx and subsequent cross-linking with glutaraldeyde. The Pt surface modified with the Ni/Al-NO3 shows a much reduced noise,

Dynamic model of amperometric biosensors. Characterisation of glucose biosensor output
Biosensors and Bioelectronics, 2001An integrated model for the characterisation of the output signal course of oxidase-bound amperometric biosensors is presented and evaluated in the case of glucose biosensors. This model integrates two earlier proposed models, the model of oxygen transducer-based biosensors, allowing the prediction of steady state parameters from the transient response

Microfabricated glucose biosensor for culture welloperation
Biosensors and Bioelectronics, 2013A water-based carbon screen-printing ink formulation, containing the redox mediator cobalt phthalocyanine (CoPC) and the enzyme glucose oxidase (GOx), was investigated for its suitability to fabricate glucose microbiosensors in a 96-well microplate format: (1) the biosensor ink was dip-coated onto a platinum (Pt) wire electrode, leading to satisfactory
