This study had investigated the possible toxicity of graphene oxide and its mechanisms on multiple myeloma cells (RPMI 8226 cells) using flow cytometry and a multifunctional microplate reader. RPMI 8226 cells were cultured with various concentrations of graphene oxide, then cell viability, malondialdehyde, glutathione and apoptosis were measured. We found that graphene oxide dose-dependently re...
Aortic graft infection is a potentially lethal complication of open and endovascular repair of aortic aneurysms. Graphene is the only existing two-dimensional material, and its unique structure gives graphene and its derivatives a plethora of original characteristics. Among other characteristics, graphene demonstrates bacteriostatic and bactericidal effects that could potentially resolve the pr...
Water purification is a vital and essential thing for human life. The presence of pollutants in water is a major threat to the environment and human health. Various materials have been proposed and used for water treatment in recent years. Recent research has shown the potential of two-dimensional materials such as graphene oxide and its composites for water purification. The goal of this proje...
Few-layer nitrogen doped graphene was synthesized originating from graphene oxide functionalized by selective oxygenic functional groups (hydroxyl, carbonyl, carboxyl etc.) under hydrothermal conditions, respectively. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) observation evidenced few-layer feature of the graphene oxide. X-ray diffraction (XRD) pattern confirmed p...
Single layer graphite, known as graphene, is an important material because of its unique two-dimensional structure, high conductivity, excellent electron mobility and high surface area. To explore the more prospective properties of graphene, graphene hybrids have been synthesised, where graphene has been integrated with other important nanoparticles (NPs). These graphene-NP hybrid structures ar...
BACKGROUND We have previously demonstrated that reduced graphene oxide (rGO) administered intravenously in rats was detected inside the hippocampus after downregulation of the tight and adherens junction proteins of the blood-brain barrier. While down-regulators of junctional proteins could be useful tools for drug delivery through the paracellular pathway, concerns over toxicity must be invest...
High quality graphitized graphene has been successfully synthesized by solid-exfoliation of graphite and a subsequent wet chemical process. The as-obtained graphene exhibits charge-discharge behaviour quite different from that of reduced graphene oxide and shows enhanced cycling and rate performance compared with commercial mesocarbon microbeads (MCMBs) for lithium ion batteries.
Because of recent research advances in nanoscience and nanotechnology, there has been a growing interest in functional nanomaterials for biomedical applications, such as tissue engineering scaffolds, biosensors, bioimaging agents and drug delivery carriers. Among a great number of promising candidates, graphene and its derivatives-including graphene oxide and reduced graphene oxide-have particu...
Nowadays, despite significant advances in the field of biomaterials for tissue engineering applications, novel bone substituents still need refinement so they can be successfully implemented into medical treatment fractures. Generally, a scaffold made synthetic polymer blended with nanofillers was proven to very promising biomaterial engineering, however choice components said remains questiona...
An in situ hydrothermal route is developed for fabricating rutile TiO2 mesocrystals/reduced graphene oxide nanosheets (TGR) hybrids in the presence of dodecylbenzenesulphonic acid (ADBS). These rutile TiO2 mesocrystals with a Wulff shape are composed of ultra-tiny rod-like subunits with the same oriented direction and closely wrapped by the nanosheets of reduced graphene oxide (RGO). It is foun...
