Indirect cytocompatibility and antibacterial properties of Zr-Cu-Ag metallic glass coatings
<p>In order to evaluate a possible antibacterial effect of the released ions, specimens (4x4 mm<sup>2</sup> square metallic glass coatings) were submerged with 7 ml of LB broth and maintained at 37°C inside a shaker (120 rpm) for 1, 5 days, following the same procedure exploited for the ions release evaluation. At each time point the supernatants were collected and used to cultivate bacteria at a defined concentration (1x10<sup>5</sup> cells/ml); bacteria cultivated with supernatants obtained from ions-free PBT were considered as control. The released ions killing activity was evaluated in terms of metabolic activity that was measured by the alamar blue assay as previously detailed. The same procedure with LB medium for hMSC was repeated. </p>

Data from: Antibacterial activity of graphene oxide nanosheet against multi drug resistant superbugs isolated from infected patients
Graphene oxide (GO) is a derivative of graphene nanosheet which is the most promising material of the decade in biomedical research. In particular, it has been known as an antimicrobial nanomaterial with good biocompatibility. In this study, we have synthesized and characterize GO and checked its antimicrobial property against different Gram-negative and Gram-positive multi drug resistant (MDR) hospital superbugs grown in solid agar-based nutrient plates with and without human serum through the utilization of agar well diffusion method, live/dead fluorescent staining and genotoxicity analysis. The main focus of the antimicrobial activity analysis is to distinguish the killing performance of GO in artificial and blood containing media because after injection into the bloodstream the activity of GO may be modified by adsorption of blood proteins or other biomolecules. No significant changes in antibacterial activity were found in these two different conditions. We also compare the bactericidal capability of GO with some commonly administrated antibiotics and in all cases the degree of inhibition is found to be higher. The data presented here are novel and show that GO is an effective bactericidal agents against different superbugs and can be used as a future antibacterial agent.

Rapid synthesis and characterization of silver-loaded graphene oxide nanomaterials and their antibacterial applications
<p>All original data used in figures and tables of the manuscript are available in the dataset, which includes the X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, scanning electron microscopy with energy dispersion spectroscopy, zeta potential analysis and antibacterial properties measurement. Ultrasound was practically used in large-scale production of water-soluble silver/graphene oxide (Ag/GO) by reducing the silver ions (Ag+) attached to graphene oxide into silver nanoparticles. The infrared and X-ray photoelectron spectra indicated that there is a strong interaction between Ag and GO. The morphology analysis showed that AgNPs having a monodisperse size was well dispersed on the surface of the GO nanosheet. The zeta potential analysis showed that the Ag/GO nanomaterials suspension has high stability. In addition, the Ag/GO nanomaterials exhibited an effective antibacterial activity against Escherichia coli and Staphylococcus aureus.</p>

The graphs indicate the measured (computed) ion count (abundance, arbitrary units) as a function of time (minutes).</p> <p> </p>
Data for: Fabrication and characterization of antibacterial coatings using an amphoteric condensed tannin,Tanfloc
<p>This dataset presents comprehensive information on the development and characterization of antibacterial polyelectrolyte multilayer (PEM) coatings incorporating tanfloc, a plant-derived condensed tannin polymer with inherent antimicrobial properties. The dataset encompasses experimental data related to the fabrication of PEMs using tanfloc as either a polyanion or a polycation, expanding the versatility of this amphoteric polymer in PEM coatings. Typically, PEMs are formed by combining a polycation and a polyanion with complementary ionic groups. However, the unique amphoteric nature of tanfloc allows for the creation of PEMs utilizing only one of its functional groups, leaving the other functional group available for imparting antibacterial activity.</p> <p>The dataset includes details on the assembly of tanfloc-containing PEMs employing various counter-polyelectrolytes, including three poly-anionic glycosaminoglycans with varying charge densities, as well as the polycations N,N,N-trimethyl chitosan and polyethylenimine. The layer-by-layer assembly of PEMs is monitored using in situ Fourier-transform surface plasmon resonance (FT-SPR), confirming stable layer-by-layer construction. Surface chemistry is assessed through X-ray photoelectron spectroscopy (XPS).</p> <p>Furthermore, this dataset provides insights into the biocompatibility of tanfloc-containing PEMs, demonstrating their support for mammalian cells. Most notably, the dataset includes extensive data on the antiadhesive and antibacterial properties of these coatings against common implant-associated pathogens, such as <em>Staphylococcus aureus</em> and <em>Pseudomonas aeruginosa</em>. The antibacterial effects observed are attributed to electrostatic interactions and the polyphenolic nature of tanfloc.</p>
