A fiber optic sensor for measuring glucose in aqueous solutions
In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...
متن کاملA glucose sensor in Candida albicans.
The Hgt4 protein of Candida albicans (orf19.5962) is orthologous to the Snf3 and Rgt2 glucose sensors of Saccharomyces cerevisiae that govern sugar acquisition by regulating the expression of genes encoding hexose transporters. We found that HGT4 is required for glucose induction of the expression of HGT12, HXT10, and HGT7, which encode apparent hexose transporters in C. albicans. An hgt4Delta ...
متن کاملInterferometric optical sensor for measuring glucose concentration.
With a specially designed probe, the phase difference between s andp polarization of light reflected under surface-plasmon resonance is measured by use of a common-path heterodyne interferometer. For specific ratios of phase difference to glucose concentration, the glucose concentration can be estimated as a function of the measured phase data. A prototype was set up to demonstrate the feasibil...
متن کاملGlucose sensor based on the LUQUEN principle
A new type of glucose sensor based on luminescence quenching (LLJQUEN) is proposed. In this LUQUEN principle the concentration induced quenching is enlarged by radiationless (excited-state) energy transfer within the luminescent material. We describe the integrated optical detection part and the chemo-optical interface, in which the concentration induced optical changes are based on the binding...
متن کاملGlucose sensor based on glucose oxidase immobilized by zirconium phosphate.
Amperometric glucose sensors were fabricated using glucose oxidase (GOx) entrapped in zirconium hydrogenphosphate (ZrP), and their performance was evaluated. Reportedly, alpha-ZrP is one of the candidates that are expected to improve the stability of enzymes immobilized on solid surfaces. We intercalated GOxs into ZrP (GOx/ZrP), cast the GOx/ZrP suspension in polyvinylalcohol on a platinum elec...
