Cellulose Surface Modification Effects on Equilibrium and Non‐Equilibrium Wetting by Water
Advanced Materials Interfaces, EarlyView.Molecular dynamics simulations of nanometer‐sized water droplets spreading on cellulose substrates show strong effects from surface chemistry on both equilibrium contact angles and spreading dynamics. ABSTRACT Chemical modification is an important route to tuning interactions between nanocellulose and its surrounding media. Specifically, it affects the

Biosensors and Bioelectronics, 2012
In vivo glucose monitoring is required for tighter glycaemic control. This report describes a new approach to construct a miniature implantable device based on a magnetic acoustic resonance sensor (MARS). A ≈ 600-800 nm thick glucose-responsive poly(acrylamide-co-3-acrylamidophenylboronic acid) (poly(acrylamide-co-3-APB)) film was polymerised on the ...

Biosensors and Bioelectronics, 2005
A novel holographic sensor system capable of detecting dynamic changes in glucose concentration has been developed. The hologram is recorded within a bio-compatible hydrogel matrix containing phenylboronic acid derivatives. On binding glucose, the colour of the hologram red-shifts to longer wavelengths as the hydrogel expands and this colour change is ...

ASAIO Journal, 1995
A major problem in development of a glucose sensor for use in an implantable artificial pancreas is the lack of reproducibility in signals from sensor to sensor. Each glucose sensor fabricated with currently used methods has a unique response to varying levels of glucose concentration and thus needs to be individually calibrated before use.

Electrocatalytic glucose sensor
Medical & Biological Engineering & Computing, 1994An electrocatalytic glucose sensor for in vivo application has been developed. The sensor is a flow-through cell with three electrodes and can be integrated into a blood vessel. The principle of measurement is based on the direct electrochemical oxidation of glucose at a membrane-covered noble-metal electrode.

Two new approaches for construction and testing of a miniature in vivo implantable glucose sensor are described. The first approach is to immobilize glucose oxidase onto a platinum wire, coated with special glass (Corning), and to cover the immobilized enzyme with a thin layer of polymer to prevent large molecules from poisoning the electrode.

A Glucose Sensor Protein for Continuous Glucose Monitoring [PDF]
Biosensors and Bioelectronics, 2010 In vivo continuous glucose monitoring has posed a significant challenge to glucose sensor development due to the lack of reliable techniques that are non- or at least minimally-invasive. In this proof-of-concept study, we demonstrated the development of a new glucose sensor protein, AcGFP1-GBPcys-mCherry, and an optical sensor assembly, capable of ...

Calibration of a Wearable Glucose Sensor
The International Journal of Artificial Organs, 1992Calibration 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 ...

Modeling the Glucose Sensor Error
IEEE Transactions on Biomedical Engineering, 2014Continuous 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.
