Promising antimicrobial and antibiofilm activities of reduced graphene oxide-metal oxide (RGO-NiO, RGO-AgO, and RGO-ZnO) nanocomposites

Abstract

Microbial infections are considered one of the most dangerous infections for humans due to their resistance to most antimicrobial agents. Nanocomposites-based reduced graphene oxide doped with metal oxides possesses a promising antimicrobial potential.

Antibacterial and antibiofilm activities of silver-decorated zinc ferrite nanoparticles synthesized by a gamma irradiation-coupled sol–gel method against some pathogenic bacteria from medical operating room surfaces

“…ZFO NPs and Ag 0.75 @ZFO NPs (the best concentration used to inhibit bacterial growth) were investigated for their antibiofilm activity against the bacterial test strains by the tubes method as defined by Elbasuney et al 44 Test tubes containing 5.0 ml of nutrient broth were inoculated with 10 μl of 0.5 McFarland (1 × 10 8 CFU ml −1 ) of the examined bacteria. Furthermore, 0.5 ml of ZFO NPs and Ag 0.75 @ZFO NPs was incorporated into the test tubes, while the same volume of water was added to the control tubes.…”

Targeted specific inhibition of bacterial and Candida species by mesoporous Ag/Sn–SnO2 composite nanoparticles: in silico and in vitro investigation

“…In another study 42 the anti bactericidal activities of Ag NPs doped in SnO 2 against E. coli and S. aureus have also been demonstrated where the efficiency of killing these organisms was found to be very less compared to the Ag–Sn/SnO 2 NPs that is used in this work. In recent study 64 comprising of reduced graphene oxide–metal oxide composite, the ZOI for C. albicans was found to be between 16–19.5 mm for different composites, i.e. RGO-NiO, RGO-AgO and RGO-ZnO which is similar to the results obtained in this study.…”

Green Biosynthesis of Selenium Nanoparticles Using Orange Peel Waste: Characterization, Antibacterial and Antibiofilm Activities against Multidrug-Resistant Bacteria

“…Nanotechnology is assumed to be the subsequent industrial revolution and is considered to have a tremendous effect on the community, economics, and the common world [5][6][7]. This field possesses great effectiveness in various sites including infection control, biomedicine, industry, wastewater treatment, and agriculture [8][9][10][11][12][13][14][15]. The environmentally friendly approach for the biosynthesis of the nanoparticle is an opportunity for appling it safely in medical fields [16][17][18].…”
