“…These carbon nanomaterials showing a planar two-dimensional morphology can be prepared at relative low cost and easily functionalized with a variety of chemical groups. Graphene and its oxidized derivative can be also combined with other materials and compounds, such as polymers, ceramics, metal and metal oxides nanostructures, etc., to yield novel composite or hybrid adducts with improved or new chemical and physical properties [11][12][13]. In this regard, the synergistic effect between graphene and metal oxide nanostructures in hybrid nanomaterials have opened new possibilities to design electrochemical biosensors with desired properties and behaviors [14].…”

Reduced graphene oxide-Sb2O5 hybrid nanomaterial for the design of a laccase-based amperometric biosensor for estriol, Electrochimica Acta http://dx. AbstractA novel reduced graphene oxide/Sb2O5 hybrid nanomaterial was prepared by a one-pot reaction process. The nanomaterial was characterized by different spectroscopic, microscopic and electrochemical techniques, demonstrating that the graphene sheets were doped with a Sb2O5 thin film. A glassy carbon electrode coated with the hybrid material was further employed as support for the covalent immobilization of laccase to develop an electrochemical biosensor for estriol. The enzyme biosensor showed high sensitivity (275 mA/M) and fast analytical response (4 s) for the hormone, with a limit of detection of 11 nM in the range of 25 nM to 1.03 µM. The biosensor showed high selectivity for the analytical detection of estriol.

“…In addition, presence of covalently bounded oxygenous groups in GO provides an appropriate platform for further chemical modifications [21]. Likewise, due to these oxygen groups, GO contains sp 2 hybridization carbon atoms and can form a thin film on glassy carbon electrode (GCE) surface via p-p interactions [22]. As GO is made by the oxidation of graphite using strong oxidizing agents, it is much cheaper than graphene.…”

“…[8][9][10][11][12][13][14] Especially, N-doped carbon has received increased attention in electrochemistry. 5,[15][16][17][18][19] For example, nitrogen-doped graphene has been developed as a promising Pt-free catalyst in the application of oxygen reduction reaction. The nitrogen-doped graphene exhibited a typical onestep, four-electron pathway and has excellent stability compared with the Pt catalyst.…”

H 2 O 2 detection plays an important role in electrochemical sensing since H 2 O 2 often acts as an intermediate product or regulator in various reactions. Nanoporous carbon (NPC) can be a potential candidate in electrochemical sensing because of its high speci¯c surface area, various pore sizes and structures. In this work, we reported the preparation of N-doped NPC derived from the highly available, accessible and recyclable plant Typha orientalis. The products have high surface area (highest surface areas of 1439.0 m 2 g À1 Þ and a number of nanopores. Highest content of nitrogen atom in the product is 3.66 at.%). Typical product exhibits high electrocatalytic activity for reduction of hydrogen peroxide. The product may have further use for glucose biosensing. We developed a low-cost, simple and readily scalable approach to prepare the excellent carbon electrocatalyst directly from crude biomass. In addition, because of high surface area and doping of nitrogen element, the product may¯nd broad applications in the¯elds of supercapacitors, lithium-ion batteries, gas uptake and so on.
