Psidium guajava leaf extract-mediated synthesis of ZnO nanoparticles under different processing parameters for hydrophobic and antibacterial finishing over cotton fabrics

Electrospun Active Biopapers of Food Waste Derived Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) with Short-Term and Long-Term Antimicrobial Performance

“…This observation suggests that the release of OEO from the PHBV matrix was improved due to the presence of the nanoparticles and/or the antimicrobial effectiveness of the inorganic nanoparticles was enhanced. In the latter case, previous studies have demonstrated that vegetal extract containing polyphenols, such as the tannins, glycosides, and flavonoids, could act as reducing and capping agents [88]. Therefore, the reaction between nanoparticles and the polyphenolic compounds carvacrol and thymol, which are the major constituents of OEO, can potentially improve the antimicrobial activity of ZnONPs.…”

Green synthesis of zinc oxide nanoparticles using different plant extracts and their antibacterial activity against Xanthomonas oryzae pv. oryzae

“…Among these biosynthesized metal oxide, zinc oxide nanoparticles have been synthesized using leaf extract of aloe barbadensis, Abutilon indicum, Melia azedarach, Indigofera tinctoria, bacterial and fungus [19][20][21][22]. Recently, zinc oxide nanoparticles have been green synthesized using: seed extracts of Nigella sativa [23], leaf extract of Psidium gujava [24], extract of Daucus carota [25], plant extract of Monsonia burkeana [26], leaf extract of Mangifera indica [27], Aspergillus terreus [28] and Halomonas elongate [29]. The antibacterial efficiency of zinc oxide nanoparticles is directly related to its size, shape, surface to volume ratio and number of oxygen vacancy sites [30,31] Although biosynthesis of zinc oxide has been reported, the potential of plant extracts as biological materials for the synthesis of nanoparticles is yet to be fully explored.…”

Moringa oleifera gum based silver and zinc oxide nanoparticles: green synthesis, characterization and their antibacterial potential against MRSA

“…Zinc oxide NPs have been prepared via leaf extract of Abutilon indicum [ 12 ], Aloe barbadensis [ 13 ], Indigofera tinctoria [ 14 ], Melia azedarach , fungus and bacteria[ 15 ]. Recently, ZnO NPs have been synthesized via green approach through leaf extract of Sidium gujava [ 16 ], seed extracts of Nigella sativa [ 17 ], root extract of Daucus carota , leaf extracts of Monsonia burkeana [ 18 ]and Mangifera indica [ 19 ], fungus Halomonas elongate and Aspergillus terreus [ 20 ]. Considering important characteristic of Moringa Oleifera plant and bio based metal nanoparticles, we developed Gum based novel NPs for their further uses in pharmaceuticals.…”
