Application	Comment	Organism
analysis	development of a metal composite material based on zirconium dioxide decorated gold nanoparticles (ZrO2 at AuNPs), copper (I) oxide at manganese (IV) oxide (Cu2O at MnO2) and immobilized choline oxidase (ChOx) onto a glassy carbon electrode (GCE) (ChOx/Cu2O at MnO2-ZrO2 at AuNPs/GCE) for enhancing the electro-catalytic property, sensitivity and stability of the amperometric choline biosensor. The ChOx/Cu2O at MnO2-ZrO2 at AuNPs/GCE displays a good electrocatalytic response to the oxidation of the byproduct H2O2 from the choline catalyzed reaction. The modified electrode also provides a wide linear range of choline concentration from 0.5 to 1000.0 microM with good sensitivity and low detection limit (0.3 microM). The apparent Michaelis-Menten constant is 0.08 mM with Imax of 0.67 microA. The choline biosensor presents high repeatability, good reproducibility, long time of use and good selectivity without interfering effects from possible electroactive species such as ascorbic acid, aspirin, amoxicillin, caffeine, dopamine, glucose, sucrose and uric acid	Alcaligenes sp.
