Research from Changchun Institute of Applied Chemistry Reveals New Findings on Peroxidases (Two-dimensional hybrid mesoporous Fe2O3-graphene nanostructures: a highly active and reusable peroxidase mimetic toward rapid, highly sensitive optical ...)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Enzymes and Coenzymes. According to news reporting out of Changchun, People's Republic of China, by NewsRx editors, research stated, "In this article, for the first time, two-dimensional hybrid mesoporous Fe2O3-graphene (mFe2O3-G) nanostructures were developed as a peroxidase mimetic with catalytic activities superior to those of mFe2O3, G, and previously reported Fe-based peroxidase mimetics. The high-surface-area mFe2O3 not only offers a large number of catalytically active sites, but also facilitates the diffusion of 3,3,5,5-tetramethylbenzidine (TMB) and H2O2 toward G surface."

Our news journalists obtained a quote from the research from the Changchun Institute of Applied Chemistry, "On the other hand, G is ?-rich and thus favors the adsorption and enrichment of TMB within these pores. These synergistic effects lead to highly improved catalytic performances. Based on these findings, a simple, rapid, and highly sensitive and selective optical detector of glucose has been developed and demonstrated in buffer solution with a pretty low detection limit of 0.5 ?M."

According to the news editors, the research concluded: "In addition, this nanosensor is reusable and can also be used for glucose detection in diluted serum."
