Since graphene nanoparticles are attracting increasing interest in relation to medical applications, it is important to understand their potential effects on humans. In the present study, we prepared graphene oxide (GO) nanoribbons by oxidative ...
This study focused on developing electrochemical sensors for ACh detection, utilizing graphene oxide (GO) and a composite of reduced graphene oxide and zinc oxide (rGO/ZnO). The synthesis involved modified Hummers' and hydrothermal methods, unveiling the formation of rGO through deoxygenation and the...
Graphene and its derivatives have been tested for their toxic effects on human erythrocytes, skin fibroblasts and different human cell lines including HepG2, A498, Caco-2, MCF-7, MDA-MB-231, SKBR3, MGC-803 and A549. Surface charge on graphene oxide (GO) has been found to play important...
Graphene oxide (GO), beyond its specialized industrial applications, is rapidly gaining prominence as a nanomaterial for modern agriculture. However, its specific effects on seed priming for salinity tolerance and yield formation in crops remain elusive. Under both pot-grown and field-grown conditions...
The gut microbiome produces metabolites that interact with the aryl hydrocarbon receptor (AhR), a key regulator of immune homoeostasis in the gut1,2. Here we show that oral exposure to graphene oxide (GO) modulates the composition of the gut microbiome i
Consequently, the potential impact of graphene and its derivatives on humans and environmental health is a matter of academic interest. However, potential hazards sufficient for risk assessment first need to be investigated. 展开 关键词: Graphene family materials Graphene Graphene oxide Reduced graphene ...
The first evidence of graphene antiviral effects was reported in 2012, when thin films of rGO − tungsten oxide were exploited for photoinactivation of bacteriophages under visible light irradiation [11]. Broad-spectrum antivirals like heparin or heparin-like drugs and sulfate-rich polymers mimic ...
Graphene oxide was discovered more or less by accident by British chemist Benjamin Brodie in 1859. In his experiments, he exposed graphite to strong acids and obtained what he calledcarbonic acid. Brodie believed that he discoveredgraphon, a new form of carbon with a molecular weight of 33. ...
Graphene oxide (GO) is one of the most well-known graphene derivatives which, due to its outstanding chemical, electrical and optical properties as well as its high oxygen content, has been recently applied in several fields such as in the construction of sensors, as antimicrobial agent for bio...
These tests with the 3-D lung model have now yielded the first results. The researchers were able to prove that no acute damage is caused to the lung if lung epithelialcellscome into contact with graphene oxide (GO) or graphene nanoplatelets (GNP). This includes responses such as sudden cel...
