“…24 , 35.56 , 43.38 , 53.88 , 57.34 , 62.82 and the peak positions were indexed at (220), (311), (400), (422), (511), (440), respectively (JCPDS card: 019-0629). 50,53,54 The face-centered cubic phase of Fe 3 O 4 nanoparticles is conrmed from the XRD spectrum, while no additional peak in the spectrum demonstrated the absence of any secondary phase in the sample. The average crystallite size of Fe 3 O 4 nanoparticles was $6 nm calculated by using the Debye-Scherrer equation: D c ¼ Kl/b cos q, where K is the space factor which is 0.9 for spherical particles, l is the wavelength, b is the peak width at half-maximum (FWHM), and q is the Bragg diffraction angle.…”

“…1B-E). The SEM image of Fe 3 O 4 nanoparticles revealed the presence of many small particles ($15 nm), 50 which were somewhat aggregated. Slightly greater size (20-30 nm) and less aggregation were observed for the M3D particles which might be attributed to the silica coating of Fe 3 O 4 nanoparticles followed by their amine (-NH 2 ) and subsequent methacrylic functionalization.…”

“…12 Some of the inorganic antibacterial materials, in particular, some single nanoparticles such as TiO 2 , ZnO, SnO 2 , MgO, CaO, Mn 3 O 4 , Fe 3 O 4 , Ag, Au, GO have been suggested to have antimicrobial properties. 4,[13][14][15][16][17] Composites from two or more of such particles might also be promising in case of possible synergistic effect. 18 Though there are many studies on nanomaterials, the majority of them only investigated whether the material works as an antibacterial agent or not.…”

Zinc oxide (ZnO) and graphene oxide (GO) nanoparticles, silver/zinc zeolite (Ag/Zn-Ze), and graphene oxide-silver (GO-Ag) nanocomposites were synthesized and characterized with X-ray powder Diffraction, Field Emission Scanning Electron Microscope and Fourier Transform-Infrared Spectroscopy. The antibacterial efficacy of these nanoparticles was evaluated against E. coli. by shake flask method and plate culture method for different concentrations. For 10 5 cells/mL initial bacterial concentration, minimum inhibitory concentration (MIC) were <160, <320, <320, and >1280 μg/mL, and antibacterial concentration at which 50% cells are inhibited (IC 50 ) were 47, 90, 78, and 250 μg/mL for Ag/Zn-Ze, GO, GO-Ag, and ZnO, respectively. Therefore, the shake flask method showed that for all nanoparticle concentrations, Ag/Zn-Ze, and GO-Ag exhibited greater inhibition efficacy, which was also highly dependent on initial bacterial concentration. However, in case of the plate culture method, similar range of inhibition capacity was found for Ag/Zn-Ze, GO-Ag, and ZnO, whereas GO showed lower potency to inhibit E. coli. In addition, GO-Ag nanocomposite exhibited more efficacy than Ag/Zn-Ze when the antibacterial surface was prepared with those. However, Ag/Zn-Ze showed no toxicity on Vero cells, whereas GO-Ag exhibited severe toxicity at higher concentrations. This study establishes GO-Ag and Ag/Zn-Ze as potent antimicrobial agents; however, their application dosage should carefully be chosen based on cytotoxic effects of GO-Ag in case of any possible physiological interaction.

“…Postreaction with sodium hypochlorite generated N-halamine groups on the imide functions of the barbituric acid, and the resulting surface displayed excellent antimicrobial activity against both Gram-positive and Gram-negative bacteria. These bifunctional nanoparticles with excellent antibacterial as well as magnetic properties not only destroyed targeted bacterial colonies but could also be recovered by applying an external magnetic field ( Akter et al, 2018 ). In a similar type of study, N-halamine functions have been generated on PDA surface, and the resulting surface has showed significantly higher antibacterial activity toward Gram-positive and Gram-negative bacteria within a brief contact time as compared to the activity displayed by the only PDA-coated substrate ( Chien et al, 2020 ).…”

The drug resistance developed by bacteria during antibiotic treatment has been a call to action for researchers and scientists across the globe, as bacteria and fungi develop ever increasing resistance to current drugs. Innovative antimicrobial/antibacterial materials and coatings to combat such infections have become a priority, as many infections are caused by indwelling implants (e.g., catheters) as well as improving postsurgical function and outcomes. Pathogenic microorganisms that can exist either in planktonic form or as biofilms in water-carrying pipelines are one of the sources responsible for causing water-borne infections. To combat this, researchers have developed nanotextured surfaces with bactericidal properties mirroring the topographical features of some natural antibacterial materials. Protein-based adhesives, secreted by marine mussels, contain a catecholic amino acid, 3,4-dihydroxyphenylalanine (DOPA), which, in the presence of lysine amino acid, empowers with the ability to anchor them to various surfaces in both wet and saline habitats. Inspired by these features, a novel coating material derived from a catechol derivative, dopamine, known as polydopamine (PDA), has been designed and developed with the ability to adhere to almost all kinds of substrates. Looking at the immense potential of PDA, this review article offers an overview of the recent growth in the field of PDA and its derivatives, especially focusing the promising applications as antibacterial nanocoatings and discussing various antimicrobial mechanisms including reactive oxygen species-mediated antimicrobial properties.
