In this study, different concentrations (0, 0.02, 0.04 and 0.06 wt. %) of Mo doped onto La2O3 nanostructures were synthesized using one-pot co-precipitation process. The aim was to study the...
Metal-based antimicrobials have the potential to profile
sustainable
solutions to infection care and health. In this study, we report the
synthesis of rGO–ZnO hybrid nanostructures by a simple co-precipitation
approach with various mass ratios of GO, and their antimicrobial potential
was assessed. The structural analysis confirms the presence of a hexagonal
wurtzite structure with peak shifting in hybrid nanostructures and
increases in crystallite size (11–24 nm). Raman spectra revealed
GO doping in the D band (1350 cm
–1
) and G band (1590
cm
–1
). Field emission scanning electron microscopy
(FESEM) and transmission electron microscopy (TEM) were performed
to investigate the surface morphologies of the synthesized sediments,
which showed a change in the morphology of ZnO from non-uniform spherical
nanoparticles to a rod-like morphology of the prepared hybrid nanostructures.
RAMAN spectra revealed that the retained functional groups on rGO
planes were significant in anchoring ZnO to rGO. At lowest and maximum
doses of ZnO, substantial bactericidal zones (
p
<
0.05) for
S. aureus
(1.55 and 1.95
mm) and
E. coli
(1.25 and 1.70 mm)
were achieved accordingly. Additionally, the inhibition regions were
2.45–3.85 mm and 3.75–6.85 mm for
S.
aureus
whereas (2.05–3.25 mm) and (2.95–3.90
mm) for
E. coli
at the lowest and maximum
concentrations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
