2015-5-1 · Synthesis of quasi spherical silver nanoparticles using purified apiin compound, extracted from henna leaf at ambient conditions (Kasthuri et al., 2009). Using green tea, Camellia sinensis extract as reducing and stabilizing agents produced gold nanoparticles and silver nanostructures in aqueous solution at ambient conditions (Nestor et al., 2008).
2019-5-25 · Growth of Sesbania seedlings in chloroaurate solution resulted in the accumulation of gold with the formation of stable gold nanoparticles in plant tissues. Transmission electron microscopy revealed the intracellular distribution of monodisperse nanospheres, possibly due to reduction of the metal ions by secondary metabolites present in cells. X-ray absorption near-edge structure and
Gold nanoparticles (GNPs) were prepared using four different plant extracts as reducing and stabilizing agents. The extracts were obtained from the following plants: Salvia officinalis, Lippia citriodora, Pelargonium graveolens and Punica granatum. The size distributions of the GNPs were measured using three different methods: dynamic light scattering, nanoparticle-tracking analysis and
