Direct Electrochemistry of Glucose Oxidase on Novel Free-Standing Nitrogen-Doped Carbon Nanospheres@Carbon Nanofibers Composite Film
We have proposed a novel free-standing nitrogen-doped carbon nanospheres@carbon nanofibers (NCNSs@CNFs) composite film with high processability for the investigation of the direct electron transfer (DET) of glucose oxidase (GOx) and the DET-based glucose biosensing. The composites were simply prepared by controlled thermal treatment of electrospun polypyrrole nanospheres doped polyacrylonitrile...
متن کاملA glucose biosensor based on direct electrochemistry of glucose oxidase immobilized on nitrogen-doped carbon nanotubes.
A novel biosensor for glucose was prepared by immobilizing glucose oxidase (GOx) on nitrogen-doped carbon nanotubes (CNx-MWNTs) modified electrode. The CNx-MWNTs membrane showed an excellent electrocatalytic activity toward the reduction of O(2) due to its diatomic side-on adsorption on CNx-MWNTs. The nitrogen doping accelerated the electron transfer from electrode surface to the immobilized GO...
متن کاملDirect Electrochemistry of Polyphenol Oxidase
The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...

متن کاملDirect Electrochemistry of Hemoglobin Immobilized in Polyvinylalcohol and Clay Composite Film Modified Carbon Ionic Liquid Electrode
Neste trabalho, líquido iônico hexaflúor-fosfato de 1-butil-3-metilimidazólio (BMIMPF6), em temperatura ambiente, foi usado como ligante na fabricação de um eletrodo líquido iônico de carbono (CILE). Hemoglobina (Hb) foi imobilizada na superfície de CILE com argila e um filme composto por polivinil álcool (PVA) pelo método camada por camada. Espectros de UV-Vis e FT-IR mostraram que Hb no filme...
