“…Spherical silver nanoparticles were produced utilizing Symplocos racemosa. Anti-microbial activity of biologically prepared silver nanoparticles was studied on P. aeruginosa (ZOI = 22 mm) [204]. Silver nanoparticles were biosynthesized by an environmentally friendly hydrothermal approach using Aloe vera aqueous leaf extract, used to evaluate antibacterial potency against P. aeruginosa (ZOI = 14.00 ± 1.00 mm), S. aureus (ZOI = 21.00 ± 1.00 mm), E. coli (ZOI = 20.00 ± 2.00 mm), and Enterobacter sp (ZOI = 32.00 ± 2.00 mm [205].…”

Nanotechnology emerged as a scientific innovation in the 21st century. Metallic nanoparticles (metal or metal oxide nanoparticles) have attained remarkable popularity due to their interesting biological, physical, chemical, magnetic, and optical properties. Metal-based nanoparticles can be prepared by utilizing different biological, physical, and chemical methods. The biological method is preferred as it provides a green, simple, facile, ecofriendly, rapid, and cost-effective route for the green synthesis of nanoparticles. Plants have complex phytochemical constituents such as carbohydrates, amino acids, phenolics, flavonoids, terpenoids, and proteins, which can behave as reducing and stabilizing agents. However, the mechanism of green synthesis by using plants is still highly debatable. In this report, we summarized basic principles or mechanisms of green synthesis especially for metal or metal oxide (i.e., ZnO, Au, Ag, and TiO2, Fe, Fe2O3, Cu, CuO, Co) nanoparticles. Finally, we explored the medical applications of plant-based nanoparticles in terms of antibacterial, antifungal, and anticancer activity.

“…The intensity of the absorption band was found to be promising as results of the formation of highly disperse nanoparticles. The successful creation of silver nanoparticles, as well as the regulation of their size and distribution, was discovered to be influenced by the solvent employed for extract synthesis [ 33 ]. The biological metabolites found in the extract play a substantial impact in the size, shape, and optical properties of silver nanoparticles [ 33 ].…”

“…This size is considerably smaller than that of the previously reported green synthesized NPs (10.2 nm and 18.12 nm) prepared using leaf extract (Raj et al, 2018;Amer and Awwad, 2021;Mehwish et al, 2021).This difference is likely due to use of different carriers, activated carbon source and/or the method and the plant bioactive components. Thus, the solvent used for the extraction of AV leaves is considered to affect the success of Pd NP synthesis and also control NP size and distribution (Panda et al, 2021).…”

New strategies for fast, efficient and environmentally friendly approaches in nanoparticle (NP) synthesis have increased the interest in less toxic green synthesis products. In this study, VA-Pd / AC nanoparticles (NPs) were synthesized using palladium (Pd), activated carbon (AC) and Viscum album (VA) aqueous extract as stabilizer / reductant. Activated carbon in the synthesis stage was obtained using the Chenopodium album (CA) plant. The structural and morphological properties of VA-Pd / AC NPs were examined using TEM and XRD analyses. Zebrafish embryo and larvae were exposed to the produced VA-Pd / AC NPs at different concentrations (10, 50, 100 and 500 mg/L) for 96 h. Embryos/larvae were examined for survival rate, hatching and malformation during development. Morever, potential neurotoxic effects were assessed histopathologically and immunohistochemically using Caspase 3 and nNOS indicators. Although the hatching rate of VA-Pd / AC NP was 100% at all concentrations, the survival rate decreased in a dose dependent manner. Histopathological analyses revealed that 10 mg/L group looked similar to the control group, whereas necrotic degenerations were observed in the 50, 100 and 500 mg/L groups in a dose- dependent manner. In addition, Caspase 3 and nNOS expressions were evaluated as negative in the control and 10 mg/L groups in immunofluorescence staining. These results provide the evidence that 500 mg/L concentration of green synthesized VA-Pd/AC NPs from Viscum album (VA) and Chenopodium album (CA) plant induces neurotoxic and tetragenonic effect on zebrafish.
