GSID: 9Qg_d-aYLZQJ
J Soto, T Hughes, YS Li - ACS omega, 2019 - ACS Publications

We created a glucose oxidase (GOx) working electrode on a silicon-on-insulator (SOI) wafer for glucose sensing. The SOI wafer was electrically connected to a copper wire, and the GOx was immobilized onto the hydrophilized SOI surface via silanization with...

Reaction-based and single fluorescent emitter decorated ratiometric nanoprobe to detect hydrogen peroxide.

Chemistry (Weinheim an der Bergstrasse, Germany)

Chen CY, Chen CT.
PMID: 24123627
Chemistry. 2013 Nov 18;19(47):16050-7. doi: 10.1002/chem.201302342. Epub 2013 Oct 10.

A novel reaction-based cross-linked polymeric nanoprobe with a self-calibrating ratiometric fluorescence readout to selectively detect H2O2 is reported. The polymeric nanoprobe is fabricated by using hydrophobic H2O2-reactive boronic ester groups, crosslinker units, and environmentally sensitive 3-hydroxyflavone fluorophores through a...

Characterisation of oxygen permeation into a microfluidic device for cell culture by in situ NMR spectroscopy.

Lab on a chip

Yilmaz A, Utz M.
PMID: 27149932
Lab Chip. 2016 May 24;16(11):2079-85. doi: 10.1039/c6lc00396f.

A compact microfluidic device for perfusion culture of mammalian cells under in situ metabolomic observation by NMR spectroscopy is presented. The chip is made from poly(methyl methacrylate) (PMMA), and uses a poly(dimethyl siloxane) (PDMS) membrane to allow gas exchange....

The Effect of Green Tea Extract on Reproductive Improvement in Estradiol Valerate-Induced Polycystic Ovarian Syndrome in Rat.

Iranian journal of pharmaceutical research : IJPR

Ghafurniyan H, Azarnia M, Nabiuni M, Karimzadeh L.
PMID: 26664389
Iran J Pharm Res. 2015;14(4):1215-33.

Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disorder in which the level of oxidative elements in blood rises. Green tea is a potent antioxidant since it contains catechins. In this study, the effect of hydro-alcoholic green tea...

Optical fiber LPG biosensor integrated microfluidic chip for ultrasensitive glucose detection.

Biomedical optics express

Yin MJ, Huang B, Gao S, Zhang AP, Ye X.
PMID: 27231643
Biomed Opt Express. 2016 Apr 28;7(5):2067-77. doi: 10.1364/BOE.7.002067. eCollection 2016 May 01.

An optical fiber sensor integrated microfluidic chip is presented for ultrasensitive detection of glucose. A long-period grating (LPG) inscribed in a small-diameter single-mode fiber (SDSMF) is employed as an optical refractive-index (RI) sensor. With the layer-by-layer (LbL) self-assembly technique,...

A facile strategy for enzyme immobilization with highly stable hierarchically porous metal-organic frameworks.

Nanoscale

Liu X, Qi W, Wang Y, Su R, He Z.
PMID: 29112218
Nanoscale. 2017 Nov 16;9(44):17561-17570. doi: 10.1039/c7nr06019j.

Metal-organic frameworks (MOFs) have drawn extensive research interest as candidates for enzyme immobilization owing to their tunable porosity, high surface area, and excellent chemical/thermal stability. Herein, we report a facile and universal strategy for enzyme immobilization using highly stable...

3D-front-face fluorescence spectroscopy and independent components analysis: A new way to monitor bread dough development.

Talanta

Garcia R, Boussard A, Rakotozafy L, Nicolas J, Potus J, Rutledge DN, Cordella CB.
PMID: 26592612
Talanta. 2016 Jan 15;147:307-14. doi: 10.1016/j.talanta.2015.10.002. Epub 2015 Oct 05.

Following bread dough development can be a hard task as no reliable method exists to give the optimal mixing time. Dough development is linked to the evolution of gluten proteins, carbohydrates and lipids which can result in modifications in...

Expression of the Aspergillus niger glucose oxidase gene in Penicillium nalgiovense.

World journal of microbiology & biotechnology

Geisen R.
PMID: 24414658
World J Microbiol Biotechnol. 1995 May;11(3):322-5. doi: 10.1007/BF00367109.

The glucose oxidase gene (god) from Aspergillus niger was expressed in Penicillium nalgiovense under control of the latter's homologous transcription signals. The GOD protein was synthesized in an active form, leading to increased glucose oxidase activity. The expression vector...
