“…Ag has an intrinsic bacterial inactivation property, whereas TiO 2 can act as photocatalyst to degrade organic dye . Modified graphene nanosheets are also widely used to carry AgNPs, which were generated in situ on the surface of graphene‐grafted poly(acrylic acid) (PAA) without additional reductant or complicated treatment …”

“…[ 96 ] Modifi ed graphene nanosheets are also widely used to carry AgNPs, which were generated in situ on the surface of graphene-grafted poly(acrylic acid) (PAA) without additional reductant or complicated treatment. [ 97 ] Although remarkable results have been obtained, the mechanism of the antibacterial effect of graphene derivatives and AgNPs hybrids remains uncertain. To elucidate this mechanism, Shi et al used two-dimensional electrophoresis and matrix assisted laser desorption ionization (MALDI)time of fl ight (TOF)/TOF analysis to estimate the protein expression profi les of P. aeruginosa after exposure to graphene-AgNPs and determined that the hybrids produced bacterial toxicity by changing protein expression.…”

Graphene materials have unique structures and outstanding thermal, optical, mechanical and electronic properties. In the last decade, these materials have attracted substantial interest in the field of nanomaterials, with applications ranging from biosensors to biomedicine. Among these applications, great advances have been made in the field of antibacterial agents. Here, recent advancements in the use of graphene and its derivatives as antibacterial agents are reviewed. Graphene is used in three forms: the pristine form; mixed with other antibacterial agents, such as Ag and chitosan; or with a base material, such as poly (N-vinylcarbazole) (PVK) and poly (lactic acid) (PLA). The main mechanisms proposed to explain the antibacterial behaviors of graphene and its derivatives are the membrane stress hypothesis, the oxidative stress hypothesis, the entrapment hypothesis, the electron transfer hypothesis and the photothermal hypothesis. This review describes contributions to improving these promising materials for antibacterial applications.

“…Recently several studies on the preparation, characterization, and antibacterial activities of carbon nanostructures combined with Ag nanoparticles have been reported. [8][9][10][11][12] While the carbon nanocomposites are a promising alternative to overcome a variety of problems resulting from the nanoparticle itself, still there are some difficulties in preparation of suitable nanocomposites. Antibacterial activities of silver nanocomposites depend on the size, shape and the degree of dispersion of AgNPs on the carbon nanostructures.…”

Carbon nanocomposites composed of carbon nanostructures and metal nanoparticles have become one of useful materials for various applications. Here we present the preparation and antibacterial activity of CNT-Ag and GO-Ag nanocomposites. Their physical properties were characterized by TEM, XPS, and Raman measurements, revealing that size-similar and quasi-spherical Ag nanoparticles were anchored to the surface of the CNT and GO. The antibacterial activities of CNT-Ag and GO-Ag were investigated using the growth curve method and minimal inhibitory concentrations against Gram-negative and Gram-positive bacteria. The antibacterial activities of the carbon nanocomposites were slightly different against Gram-positive and Gramnegative bacteria. The proposed mechanism was discussed.

“…[1] A few years ago, Okamura et al [2] coined the term "giant nanomembrane" to denote quasi-2D selfsupporting 1-100 nm thick membranes, with size-to-thickness aspect ratio greater than 10 6 , huge surface to volume ratio, low weight, high flexibility, robustness, and in most cases, transparency. [3] NFs made of conventional polymers have been proposed as wound-suturing nanopatches in open or minimal invasive surgery, [2] platforms for cell-substrate interactions, [3] sensors, [4] nanobiological reactors, [5] biointerfaces for cellular matrices, [6] antimicrobial platforms, [7] drug-release devices for burn treatment, tissue engineering scaffolds, and other applications [8,9,10] and for localized therapies. [11] The interest toward NFs is also due to peculiar properties such as their conformal adhesion to uneven surfaces, and the possibility of injecting them through a syringe.…”

Polymeric free-standing nanofilms are emerging as appealing materials for many applications, including biomedical ones. This communication describes a new and versatile method to obtain self-supported plasma-deposited coatings. Coupling a soluble sacrificial layer with low or atmospheric pressure plasma processes, free-standing films have been prepared. Vancomycin-embedded bio-composite coatings have been deposited at atmospheric pressure with an aerosol-assisted plasma process, while PolyEthylene Oxide-like (antifouling and cross-linked) coatings and silver-containing (antibacterial) nanocomposite coatings have been plasma-deposited at low pressure. The described approach can certainly be extended to many possible free-standing nanofilms of different nature that can be synthesized by means of customized plasma processes, and it is a valid alternative to conventional wet methods to nanofilm synthesis
