Abstract
The precipitation process was used to synthesize ZnO nanoparticles (ZnO NPs), which were functionalized with fifteen amino acids and three surfactants. X-ray diffraction (XRD), field emission scanning microscopy (FESEM) with energy-dispersive X-ray spectroscopy, Fourier transformed infrared spectroscopy (FTIR), Raman spectroscopy, and UV-Vis spectroscopy were used to evaluate the synthesized and functionalized ZnO NPs. The characterization of the produced ZnO using XRD and FESEM revealed the development of a nanoscale hexagonal crystal, and the spectroscopic methods validated the presence of IR functional groups, Raman phase mode, and UV optical absorbance. The ZnO samples that had been functionalized demonstrated deformation in a surface morphology while maintaining chemical stability. The functionalization procedure effectively increases the inhibitory efficacy of NPs against (Accession No. MZ435922) and (Accession No. MZ435863), as demonstrated by the antifungal activity. The findings of current work provide a foundation for improving the biological activity of NPs against fungi by modifying them with active medium and boosting their anti-microorganism and antioxidant activity.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
