By a News Reporter-Staff News Editor at Biotech Week -- Investigators publish new report on Hydrogen. According to news reporting out of Changsha, People's Republic of China, by NewsRx editors, research stated, "Carbon nanomaterials are typically used in electrochemical biosensing applications for their unique properties. We report a hollow graphitic nanocapsule (HGN) utilized as an efficient electrode material for sensitive hydrogen peroxide detection."
Our news journalists obtained a quote from the research from Hunan University, "Methylene blue (MB) molecules could be efficiently adsorbed on the HGN surfaces, and this adsorption capability remained very stable under different pH regimes. HGNs were used as three-dimensional matrices for coimmobilization of MB electron mediators and horseradish peroxidase (HRP) to build an HGN-HRP-MB reagentless amperometric sensing platform to detect hydrogen peroxide. This simple HGN-HRP-MB complex demonstrated very sensitive and selective hydrogen peroxide detection capability, as well as high reproducibility and stability."
According to the news editors, the research concluded: "The HGNs could also be utilized as matrices for immobilization of other enzymes, proteins or small molecules and for different biomedical applications."
