Synthesis, dispersion, and cytocompatibility of graphene oxide and reduced graphene oxide

Colloids and Surfaces B: Biointerfaces, 2012
The 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.

Effects of oxidation on the defect of reduced graphene oxides in graphene preparation

Journal of Colloid and Interface Science, 2015
The relationship between the defects of reduced graphene oxide (RGO) and the oxidation degree of graphite in the preparation of graphene with chemical conversion method has been studied in this work. This study was performed on an artificial graphite through the measurements of X ray diffraction, Raman spectroscopy and particle size analysis.

The Potential of Graphene Oxide and Reduced Graphene Oxide in Diagnosis and Treatment of Cancer

Current Medicinal Chemistry, 2022
Abstract: Nanotechnology is a pioneer field of study for engineering smart nanosystems in targeted diagnosis and treatment in cancer therapy. Effective treatment for various types of solid tumors should ideally target malignant cells and tissue while having no effect on healthy cells in the body.

SINTESIS GRAPHENE OXIDE DAN REDUCED GRAPHENE OXIDE

PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL) SNF2016 UNJ, 2016
Graphene oxide (GO) and reduced graphene oxide (rGO) have been synthesized chemically from graphite powder. Graphite powder was oxidized with strong oxidator agent molekul  to get graphite oxide, this process was called by Hummer’s methode. Graphite oxide was dispersed in water with ultasonic vibrator to exfoliated graphite oxide layers, and ...

Reduced Graphene Oxide Molecular Sensors

Nano Letters, 2008
We demonstrate reduced graphene oxide as the active material for high-performance molecular sensors. Sensors are fabricated from exfoliated graphene oxide platelets that are deposited to form an ultrathin continuous network. These graphene oxide networks are tunably reduced toward graphene by varying the exposure time to a hydrazine hydrate vapor.

Fibers of reduced graphene oxide nanoribbons

Nanotechnology, 2012
Reduced graphene oxide nanoribbon fibers were fabricated by using an electrophoretic self-assembly method without the use of any polymer or surfactant. We report electrical and field emission properties of the fibers as a function of reduction degree.

Adsorption of VOCs on reduced graphene oxide

Journal of Environmental Sciences, 2018
A modified Hummer's method was adopted for the synthesis of graphene oxide (GO) and reduced graphene oxide (rGO). It was revealed that the modified method is effective for the production of GO and rGO from graphite. Transmission electron microscopy (TEM) images of GO and rGO showed a sheet-like morphology.
