Eco-friendly approach towards green synthesis of zinc oxide nanocrystals and its potential applications

Abstract

In the present study, we investigated a novel green route for synthesis of zinc oxide (ZnO) nanocrystals using Prunus × yedoensis Matsumura leaf extract as a reducing agent without using any surfactant or external energy. Standard characterization studies were carried out to confirm the obtained product using UV-Vis spectra, SEM-EDS, FTIR, TEM, and XRD. In addition, the synthesized ZnO nanocrystals were coated onto fabric and leather samples to study their bacteriostatic effect against odor-causing bacteria Brevibacterium linens and Staphylococcus epidermidis. Zinc oxide nanocrystal-coated fabric and leather showed good activity against both bacteria.

“…The appearance of peaks in the region of 406 cm -1 is ascribed to the formation of metal-oxygen bond (Kavyashree et al, 2015). The SEM micrographs (Figure 2C) shows the SaZnO NPs formed are of highly agglomerated, to form a well-defined triangular to nearly hexagonal shape in nature, which can be attributed to wurtzite structure of ZnO NPs which is in accordance with recent findings (Velmurugan et al, 2016; Ahmed et al, 2017).…”

Bio-extract-mediated ZnO nanoparticles: microwave-assisted synthesis, characterization and antidiabetic activity evaluation

“…The utilized Vaccinium arctostaphylus L. fruit extract is rich in active constituents, including anthocyanins, flavonoids, polyphenols and vitamins. Phenolic compounds such as gallic, ellagic, p-hydroxybenzoic, m-hydroxybenzoic, chlorogenic, and sinapic acids [50] have particularly significant role in biosynthesis of ZnO NPs [40]. It is believed that the hydroxyl groups of phenolic compounds form complexes through chelating with Zn 2þ ions, forming a p-track conjugation effect.…”

“…Moreover, biosynthesis methods are green alternatives whereof the outputs are bio-friendly, very soluble in aqueous medium, and free of contaminations, which can actually provide better defined nanoparticles in size and morphology [39]. The bio-agent can provide a desirable reaction medium and act as reducing agent in synthesis process [40,41]. This method offers the application of biological agents including enzymes, microorganisms, and plant extracts for the synthesis of NPs [40,42].…”

Green synthesis using plant extract, in particular, has attracted a great deal of research interest as they led to facile production of more stable nanoparticles [41,43].…”

“…Green synthesis using plant extract, in particular, has attracted a great deal of research interest as they led to facile production of more stable nanoparticles [41,43]. The extracts of potato, tomato, Corymbia citriodora leaf, Ziziphus nummularia leaf, Prunus yedoensis Matsumura leaf and Abrus precatorius seed, been used as promising choices for facile green synthesis of ZnO NPs in the reported literature [19,20,23,40,41,44].…”
