Enhanced antibacterial activity through the controlled alignment of graphene oxide nanosheets
Open accessAbstract
Significance: In biomedical and environmental applications, as well as manufacture and disposal, the interaction of graphene-based nanomaterials (GBNs) with living cells is inevitable and sometimes crucial. While the cytotoxic properties of GBNs are well established, the mechanisms behind the cytotoxicity remain controversial. In this study, we first utilize a magnetic field to form films with aligned graphene oxide (GO), showing that the alignment of sharp GO edges plays a crucial role in the antibacterial activity. We then demonstrate using model systems that GO unequivocally induces physical disruption of lipid bilayers and that oxidation stems from a direct electron transfer mechanism. Altogether, our results elucidate the physicochemical, edge-based cytotoxicity of GBNs, while providing guidance for the design of engineered surfaces using GBNs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
