“…Multifunctional, recyclable, synergistic nanocomposites with high efficiency toward Gram-negative bacterium, E. coli , and Gram-positive bacterium, S. aureus , were prepared by growing both iron oxide nanoparticles (NPs) and silver nanoparticles (Ag NPs) on the surface of graphene oxide GO [ 37 ]. Several types of RGO-based nanocomposites were synthesized according to the method of Hummer, modified by us: RGO/Ag [ 50 ], RGO/Ag/Cu [ 51 ], and RGO/ZnO/TiO2/SiO2 [ 52 ] demonstrated increased antimicrobial activity, compared to RGO. Gr/cadmium sulfide nanocomposites, obtained by two-step solve-thermal process, were reported with experimentally demonstrated inactivation performance toward E. coli in the presence of humic acid, under visible light irradiation [ 38 ].…”

Antibiofouling Activity of Graphene Materials and Graphene-Based Antimicrobial Coatings

Microbial adhesion and biofilm formation is a common, nondesirable phenomenon at any living or nonliving material surface in contact with microbial species. Despite the enormous efforts made so far, the protection of material surfaces against microbial adhesion and biofilm formation remains a significant challenge. Deposition of antimicrobial coatings is one approach to mitigate the problem. Examples of such are those based on heparin, cationic polymers, antimicrobial peptides, drug-delivering systems, and other coatings, each one with its advantages and shortcomings. The increasing microbial resistance to the conventional antimicrobial treatments leads to an increasing necessity for new antimicrobial agents, among which is a variety of carbon nanomaterials. The current review paper presents the last 5 years’ progress in the development of graphene antimicrobial materials and graphene-based antimicrobial coatings that are among the most studied. Brief information about the significance of the biofouling, as well as the general mode of development and composition of microbial biofilms, are included. Preparation, antibacterial activity, and bactericidal mechanisms of new graphene materials, deposition techniques, characterization, and parameters influencing the biological activity of graphene-based coatings are focused upon. It is expected that this review will raise some ideas for perfecting the composition, structure, antimicrobial activity, and deposition techniques of graphene materials and coatings in order to provide better antimicrobial protection of medical devices.

“…For its antimicrobial action, graphene is used in the packaging of foodstuffs or to cover biomedical equipment where bacterial multiplication on the surface is undesirable. It was shown that with modification of graphene by metal or metal oxide nanoparticles, a synergic effect occurs and the antibacterial action is more effective due to the fine structure, new surface characteristics and durability of the composite obtained [9]. Polymer-graphene based composites also show prospective antibacterial properties [10].…”

In the present study, we report on the facile prepared nanocomposites of reduced graphene oxide RGO with Cu and Ag. The synthesis was performed through an environmentally friendly and easy method by simultaneous reduction in solutions containing Cu2+ or Ag+ and graphene oxide (GO) using zinc powder as a reducing agent in aqueous acidic media. The composites are characterized by powder X-ray diffraction, low-temperature nitrogen adsorption, X-ray photoelectron and FTIR and Raman spectroscopies, as well as Scanning and Transmission electron microscopies. The antibacterial activity of the composites was tested for Staphylococcus aureus, Escherichia coli and antifungal activity for Candida albicans. The cytotoxicity of the materials was studied towards two types of eukaryotic cells—MDCK II and A549 cell lines. The composites obtained consist of homogeneously distributed Cu and Ag nanoparticles on the surface of graphene sheets and manifest good antimicrobial activity and high cytotoxicity. The results clearly show that both metal–RGO composites can be successfully used as antimicrobial and anticancer agents.
