Antibacterial Activity of Monolayer Graphene Film to Standardised Staphylococcus Aureus Strains

Testing the antibacterial activity of monolayer graphene film on a copper substrate that was covered with a Staphylococcus aureus culture, Gram-positive bacteria recognized for resilience in external environment found that the bacterial suspension’s phisical contact with the a large-area graphene produces significant disturbances of the microorganism’S vital processes.

Electron Transfer Directed Antibacterial Properties of Graphene Oxide on Metals

It is shown that superior antimicrobial properties of natural shellac-derived graphene oxide (GO) coatings is obtained on metallic films, such as Zn, Ni, Sn, and steel.

Graphene Oxide-Coated Surface: Inhibition of Bacterial Biofilm Formation due to Specific Surface–Interface Interactions

It is demonstrated that beside reactive oxygen species-mediated oxidative stress, the physical properties of the GO-coated substrate effectively inactivate bacterial cell proliferation, which forms biofilms.

Large-area chemical vapor deposition-grown monolayer graphene-wrapped silver nanowires for broad-spectrum and robust antimicrobial coating

New types of antimicrobial systems are urgently needed owing to the emergence of pathogenic microbial strains that gain resistance to antibiotics commonly used in daily life and medical care. In this

Recent advancements in the use of graphene and its derivatives as antibacterial agents are reviewed and contributions to improving these promising materials for antibacterial applications are described.

Graphene/SiO2 nanocomposites: The enhancement of photocatalytic and biomedical activity of SiO2 nanoparticles by graphene

The exceptional conducting nature of graphene makes it a viable candidate for enhancing the effectiveness of photocatalytic and biomedical nanomaterials. Herein, the immobilization of monodispersed

Graphene Coating as an Effective Barrier to Prevent Bacteria-Mediated Dissolution of Gold

The interaction of biofilms with metallic surfaces produces two biologically induced degradation processes of materials: microbial induced corrosion and bioleaching. Both phenomena affect most



Toxicity of graphene and graphene oxide nanowalls against bacteria.

It was found that the cell membrane damage of the bacteria caused by direct contact of theacteria with the extremely sharp edges of the nanowalls was the effective mechanism in the bacterial inactivation.

Graphene oxide: a nonspecific enhancer of cellular growth.

This study conclusively demonstrates that graphene oxide does not have intrinsic antibacterial, bacteriostatic, and cytotoxic properties in both bacteria and mammalian cells, and graphene oxide acts as a general enhancer of cellular growth by increasing cell attachment and proliferation.

Graphene-based antibacterial paper.

Graphene-based nanomaterials can effectively inhibit the growth of E. coli bacteria while showing minimal cytotoxicity and it is demonstrated that macroscopic freestanding GO and rGO paper can be conveniently fabricated from their suspension via simple vacuum filtration.

Antibacterial activity of graphite, graphite oxide, graphene oxide, and reduced graphene oxide: membrane and oxidative stress.

Health and environmental impacts of graphene-based materials need to be thoroughly evaluated before their potential applications. Graphene has strong cytotoxicity toward bacteria. To better

Enhanced room-temperature corrosion of copper in the presence of graphene.

It is shown that a graphene coating can, on the contrary, accelerate long-term oxidation of an underlying copper substrate in ambient atmosphere at room temperature.

Destructive extraction of phospholipids from Escherichia coli membranes by graphene nanosheets.

It is shown experimentally and theoretically that pristine graphene and graphene oxide nanosheets can induce the degradation of the inner and outer cell membranes of Escherichia coli, and reduce their viability.

Wrapping bacteria by graphene nanosheets for isolation from environment, reactivation by sonication, and inactivation by near-infrared irradiation.

Graphene nanosheets may potentially serve as an encapsulating material for delivery of such microorganisms and as an effective photothermal agent for inactivation of the graphene-wrapped microorganisms.

Large-Area Synthesis of High-Quality and Uniform Graphene Films on Copper Foils

It is shown that graphene grows in a self-limiting way on copper films as large-area sheets (one square centimeter) from methane through a chemical vapor deposition process, and graphene film transfer processes to arbitrary substrates showed electron mobilities as high as 4050 square centimeters per volt per second at room temperature.
