A Novel Choline Biosensor Based on Immobilization of Enzyme Choline Oxidase on the β-Ga2O3 Nanowires Modified Working Electrode
This article is a report on a novel and high-stability biosensor with minor interference effects of surface modification of working electrode with β-Ga2O3 nanowires (NWs) on choline oxidase biosensor were investigated in an electrochemical detection system. β-Ga2O3 NWs were materialized on the silicon substrate in a catalyst-free growth mechanism. The β-Ga2O<sub...

متن کاملIntracellular distribution of choline oxidase.
Recently considerable attention has been centered upon the relation of choline oxidase activity to folic acid, the Leuconostoc citrovorum factor (LCF), ascorbic acid, and vitamin B,,. From this laboratory it has been indicated that rat liver choline oxidase can be stimulated in vitro under certain conditions by these factors, especially if the activity of the enzyme is previously decreased by d...
متن کاملFluorometric determination of ethanol in liquor samples by flow-injection analysis using an immobilized enzyme-reactor column with packing prepared by coupling alcohol oxidase and peroxidase onto chitosan beads.
A flow-injection system was developed for the determination of ethanol with an immobilized enzyme-reactor column. This system, which consisted of hand-made reactor columns packed with alcohol oxidase and horseradish peroxidase immobilized onto chitosan beads, and a fluorometric detector, was applied to the determination of ethanol in liquor samples. Under the recommended conditions, the ethanol...
متن کاملOxidation of choline-like substances by rat liver preparations; inhibitors of choline oxidase.
The work of Moyer and du Vigneaud (1) has demonstrated that, of a considerable number of compounds related to choline, choline itself, betaine, its sulfur analogue dimethylthetin, and the dimethylethyl analogue of choline, i.e. dimethylethyl-P-hydroxyethylammonium chloride, are the only ones which will permit rat growth on a methionine-free homocystinecontaining diet. Subsequent work by Dubnoff...
