A viscosity-dependent affinity sensor for continuous monitoring of glucose in biological fluids

Jean-Michel Sallese, Peter Ryser, Eric Meurville, Christophe Boss

We present a viscometric affinity biosensor for continuous monitoring of glucose in biological fluids such as blood and plasma. The sensing principle of this chemico-mechanical sensor is based upon the viscosity variation of a sensitive fluid with glucose ...

Amperometric biosensor with nanostructured electrodes by using multi-alled carbon nanotubes for glucose detection in cell culture medium

Giovanni De Micheli, Sandro Carrara, Cristina Boero

The monitoring of metabolic compounds such as glucose is largely reported in literature. The applications of this type of analysis are mainly related to clinical purposes, e.g. in diabetes pathology, where a lot of studies are presented in literature. Rece ...

Size-Selective Diffusion in Nanoporous but Flexible Membranes for Glucose Sensors

Peter Ryser, Eric Meurville, Nao Takano

A series of nanoporous membranes prepared from polyethylene-block-polystyrene were applied for size-selective diffusion of glucose and albumin molecules. Millimeter-sized test cells for characterization of such molecular diffusions were designed assuming a ...

Sustained neuronal activation raises oxidative metabolism to a new steady-state level: Evidence from 1H NMR spectroscopy in the human visual cortex

Rolf Gruetter

To date, functional 1H NMR spectroscopy has been utilized to report the time courses of few metabolites, primarily lactate. Benefiting from the sensitivity offered by ultra-high magnetic field (7 T), the concentrations of 17 metabolites were measured in th ...

Metabolic compartmentalization in the human cortex and hippocampus: evidence for a cell- and region-specific localization of lactate dehydrogenase 5 and pyruvate dehydrogenase

Pierre Magistretti

BACKGROUND: For a long time now, glucose has been thought to be the main, if not the sole substrate for brain energy metabolism. Recent data nevertheless suggest that other molecules, such as monocarboxylates (lactate and pyruvate mainly) could be suitable ...

Implantable glucose sensor : an approach based on a rotating microviscometer combined with a sensitive liquid containing dextran and Concanavalin A

Simon Albert Künzi

For more than thirty years there has been a high demand for glucose measuring devices to replace the finger pricking methods and to improve the life quality of diabetics. Three approaches are possible, electrochemical, electromagnetic (including optical), ...

Effect of chronic hypoglycaemia on glucose concentration and glycogen content in rat brain: A localized 13C NMR study

Rolf Gruetter, Hongxia Lei

While chronic hypoglycaemia has been reported to increase unidirectional glucose transport across the blood-brain barrier (BBB) and to increase GLUT1 expression at the endothelium, the effect on steady-state brain d-glucose and brain glycogen content is cu ...
