TL;DR: This critical review covers the present state of the art in optical sensing of glucose using methods based on monitoring the optical properties of intrinsically fluorescent or labeled enzymes, their co-enzymes and co-substrates.
Journal ArticleDOI
Nanogold-plasmon-resonance-based glucose sensing.
TL;DR: The authors' plasmonic-type glucose nanosensors with regard to particle stability, pH effects, the dynamic range for glucose sensing, and the observation wavelength are optimized to be compatible with clinical glucose requirements and measurements.

Hiroyuki Kudo,Takanori Sawada,Elito Kazawa,Hiromichi Yoshida,Yasuhiko Iwasaki,Kohji Mitsubayashi +5 more
TL;DR: A novel biosensor for glucose measurement using functional polymers was fabricated and tested and showed novel functions of flexibility and it was stretchable so that the sensor could normally work when it was released after expanding to 120% longer than that of normal length.

Journal ArticleDOI
Kinetics and mechanism of action of glucose oxidase.
TL;DR: The results of electron spin resonance and optical spectrophotometry correlated with rapid reaction studies, to establish whether or not intermediate forms of the enzyme react at rates sufficient to account for its catalytic activity as discussed by the authors.
Journal ArticleDOI
Fluorescence and optical characteristics of reduced flavines and flavoproteins.
TL;DR: In this paper, the authors discussed the fluorescence and optical properties of reduced flavins and flavoproteins and found that the 4a,5-dihydroflavin chromophore exhibits a strong fluorescence that is maximal around 520 nm.
Journal ArticleDOI
Affinity sensor: A new technique for developing implantable sensors for glucose and other metabolites
TL;DR: Preliminary tests of the sensor indicated the feasibility of the approach, and sensitivity to glucose in the physiologic range was obtained, but further work will be required to optimize the sensitivity and response time of the sensors.
Journal ArticleDOI
Optical sensors. Part 34. Fibre optic glucose biosensor with an oxygen optrode as the transducer
TL;DR: A biosensor for the continuous determination of glucose was presented and the consumption of oxygen was measured by following, via fibre optic bundles, the changes in the fluorescence of an oxygen-sensitive dye whose fluorescence is quenched dynamically by molecular oxygen.
Journal ArticleDOI
Fibre-optic glucose sensor with a pH optrode as the transducer
TL;DR: In this paper, an enzyme optrode capable of continuously monitoring glucose concentrations is presented, where the enzyme catalyses the oxidation of glucose to give gluconic acid, which, in turn, lowers the pH in the microenvironment of the sensor.
