Sensitive D-amino acid biosensor based on oxidase/peroxidase system mediated by pentacyanoferrate-bound polymer.
A sensitive d-amino acid oxidase (DAAO)/peroxidase (POD) bienzyme biosensor is constructed, in which pentacyanoferrate-bound poly(1-vinylimidazole) polymer (PVI[Fe(CN)5]) is selected as a mediator. Reductive current of PVI[Fe(CN)5] related to the H2O2 concentration generated in the DAAO reaction was measured at -0.1V vs. Ag|AgCl with DAAO/POD/PVI[Fe(CN)5]-modified electrode. The result revealed...
متن کاملAmperometric biosensor based on reductive H2O2 detection using pentacyanoferrate-bound polymer for creatinine determination.
Pentacyanoferrate-bound poly(1-vinylimidazole) (PVI[Fe(CN)5]) was selected as a mediator for amperometric creatinine determination based on the reductive H2O2 detection. Creatinine amidohydrolase (CNH), creatine amidohydrolase (CRH), sarcosine oxidase (SOD), peroxidase (POD), and PVI[Fe(CN)5] were crosslinked with poly(ethylene glycol) diglycidyl ether (PEGDGE) on a glassy carbon (GC) electrode...
متن کاملSynthesized Bimetallic Electrocatalyst for Oxygen Reduction Reaction in Polymer Electrolyte Fuel Cells
In the present study, a step by step process was applied to synthesize bimetallic electrocatalyst (Ru and Pt on VulcanXC-72R). This process can reduce the amount of platinum and increase the gas diffusion electrode (GDE) performance in the cathodic reaction of polymer electrolyte membrane fuel cells (PEMFCs). Using the impregnation by hydrothermal synthesis method, a series of electrocatalysts ...
متن کاملCreatinine Biosensor Based on Reductive H2O2 Detection Using Pentacyanoferrate-bound Polymer
Creatinine is the final product of creatine metabolism in muscle of mammals, and mainly filtered out of blood in kidneys. The creatinine levels are related to the state of renal function, thyroid malfunction and muscular disorders. This indicates the importance of creatinine measurements in blood or urine. The current clinical determination of creatinine is based on Jaffe reaction [1]. However,...
متن کاملBilirubin oxidase based enzymatic air-breathing cathode: Operation under pristine and contaminated conditions.
The performance of bilirubin oxidase (BOx) based air breathing cathode was constantly monitored over 45 days. The effect of electrolyte composition on the cathode oxygen reduction reaction (ORR) output was investigated. Particularly, deactivation of the electrocatalytic activity of the enzyme in phosphate buffer saline (PBS) solution and in activated sludge (AS) was evaluated. The greatest drop...
