“…31 In this work, we discovered that the synthesized AgNPs match the face-centered cubic crystal structure of metallic silver. This result is consistent with the results reported by Jain et al, 1 Cruz et al, 2 and Gilaki. Energy-dispersive spectroscopy is used to gain further insight into the features of AgNPs.…”

Development of a green chemistry process for the synthesis of silver nanoparticles has become a focus of interest. This would offer numerous benefits, including ecofriendliness and compatibility for biomedical applications. Here we report the synthesis of silver nanoparticles from the reduction of silver nitrate and an aqueous extract of the lichen Parmotrema praesorediosum as a reductant as well as a stabilizer. The physical appearance of these silver nanoparticles was characterized using ultraviolet-visible spectroscopy, electron microscopy, energy-dispersive spectroscopy, and X-ray diffraction techniques. The results show that silver nanoparticles synthesized using P. praesorediosum have an average particle size of 19 nm with a cubic structure. The antibacterial activity of the synthesized silver nanoparticles was tested against eight micro-organisms using the disk diffusion method. The results reveal that silver nanoparticles synthesized using P. praesorediosum have potential antibacterial activity against Gram-negative bacteria.

“…Bioactive compounds from plants are the other source for natural reducing and capping agents. Bioactive compounds from various herbs and plants such as Piper longum, Crataegus douglasii, Nephelium lappaceum, Lippia citriodora, Plukenetia volubilis, Chrysanthemum morifolium, Medicago sativa, Sterculia foetida, Cinnamon zeylanicum, Alcea rosea, Zataria multiflora, Matricaria chamomilla and black tea were used for synthesis of AgNPs in a sustainable manner (Cruz et al, 2010;Vivekanandhan et al, 2014;Reddy et al, 2014;Ghaffari-Moghaddam and Hadi-Dabanlou, 2014;Kumar et al, 2015;He et al, 2013;Lukman et al, 2011;Rajasekharreddy and Rani, 2014;Sathishkumar et al, 2009;Ebrahiminezhad et al, 2016b;2016e;2016c).…”

Silver nanoparticles (AgNPs) retained vast applications in science and technology. Due to the vast application of these particles in various disciplines, there is an interest for synthesis of AgNPs in an environmentally friendly and economic manner. For the first time we were used Mediterranean cypress (Cupressus sempervirens) leaf aqueous extract for biosynthesis of AgNPs. Prepared particles were in various shapes and their diameters were ranging from 10 to 80 nm. TEM micrographs were shown that AgNPs are capped with a biologic matrix. FTIR analysis indicates hydrophilic functional groups in the capping matrix which can improve the stability of AgNPs.

“…Suman et al 20 used extract from Morinda citrifolia roots at room temperature, and the size of the resultant GNPs was in the range of 8-17 nm, while Shankar et al 21 obtained GNPs with different shapes in the size range of 20-40 nm using Pelargonium graveolens (PeG) leaves and its endophytic fungus. Basavegowda et al 22 synthesized GNPs in the size range of 10-50 nm using Punica granatum (PuG) extract as a reducing agent and examined its antibacterial properties, while Fierascu et al 23 synthesized 10 nm GNPs from Salvia officinalis (SO) extract and Cruz et al 24 synthesized silver NPs with a size distribution in the range of 15-30 nm from Lippia citriodora (LC). The study presented here describes a detailed investigation of the synthesis and characterization of GNPs using four different plant extracts.…”

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 analysis of scanning electron microscopy images. The three methods yielded similar size distributions. Biocompatibility was examined by correlation of L-cell growth in the presence of different amounts of GNPs. All GNPs showed good biocompatibility and good stability for over 3 weeks. Therefore, they can be used for imaging and drug-delivery applications in the human body. High-resolution transmission electron microscopy was used to view the shapes of the larger GNPs, while infrared spectroscopy was employed to characterize the various functional groups in the organic layer that stabilize the particles. Finally, active ingredients in the plant extract that might be involved in the formation of GNPs are proposed, based on experiments with pure antioxidants that are known to exist in that plant.
