Anticancer activity of graphene oxide-reduced graphene oxide-silver nanoparticle composites
Journal of Colloid and Interface Science, 2017In the present study, a chemical route was employed to synthesize graphene oxide (GO)-reduced graphene oxide (rGO)-Ag nanoparticle (AgNP) composites from graphite and AgNO3 using vitamin C as reducing agent. Powder X-ray diffraction pattern and field emission scanning electron microscope images revealed that the AgNP were uniformly distributed on the ...

Synthesis, dispersion, and cytocompatibility of graphene oxide and reduced graphene oxide
Colloids and Surfaces B: Biointerfaces, 2012The synthesis, characterization, and toxicity of graphene oxide and reduced graphene oxide are reported. Prior to the cytocompatibility tests the stability of the suspensions in a wide range of concentrations (3.125-100 μg/mL) of three different dispersants is studied.

Rapidly reducing graphene oxide
Science, 2016Nanomaterials The reduction of exfoliated graphene oxide platelets can produce graphene for applications in materials, energy storage, and catalysis. However, reduction methods often leave a substantial fraction of oxygenated functional groups in graphene, lowering its electrical conductivity. Voiry et al.

3D Printing of Reduced Graphene Oxide Nanowires
Advanced Materials, 20143D printing of reduced graphene oxide (rGO) nanowires is realized at room temperature by local growth of GO at the meniscus formed at a micropipette tip followed by reduction of GO by thermal or chemical treatment. 3D rGO nanowires with diverse and complicated forms are successfully printed, demonstrating their ability to grow in any direction and at ...

Advanced Materials, 2013
14–19 ] The conductor-insulator composites are attracting much attention for potential applications of charge-storage capacitors, thin-fi lm transistors, and antistatic materials owing to their unique properties, i.e., a dramatic increase in dielectric constant in the conductor-insulator composite fi lms near the percolation threshold.

Electronic structure of graphene oxide and reduced graphene oxide monolayers
Applied Physics Letters, 2012Graphene oxide (GO) monolayers obtained by Langmuir Blodgett route and suitably treated to obtain reduced graphene oxide (RGO) monolayers were studied by photoelectron spectroscopy. Upon reduction of GO to form RGO C1s x-ray photoelectron spectra showed increase in graphitic carbon content, while ultraviolet photoelectron spectra showed increase in ...

Permselective properties of graphene oxide and reduced graphene oxide electrodes
Carbon, 2014Abstract Although graphene-based materials have a number of excellent properties, their permselective properties have not yet been reported. In this work, graphene oxide (GO) and its reduced form (rGO) with the C:O ratios of 2.3:1 and 10.5:1, respectively were coated on glassy carbon electrodes (GCES) and subsequently evaluated by cyclic voltammetry ...
