“…In the present investigation, the synthesized silver nanoparticles show strong absorption in the range 2.5-4 keV. Similar results were reported earlier and the formation of silver nanoparticles was in the range 2-4 keV using Artemisia nilagirica leaf and Artocarpus heterophyllus seed extracts by Jagtap and Bapat (2013) and Vijaykumar et al (2013).…”

In this paper, an aqueous extract of fresh leaves of Pedalium murex was used for the synthesis of silver (Ag) nanoparticles. Different biological methods are gaining recognition for the production of silver nanoparticles (AgNPs) due to their multiple applications. The use of plants in the green synthesis of nanoparticles emerges as a cost-effective and eco-friendly approach. Characterization of nanoparticles was done using different methods, which include; ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR), powder X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray analysis (EDAX), fluorescence emission spectroscopy, transmission electron microscope (TEM), dynamic light scattering (DLS), zeta potential and antibacterial activity. UV-visible spectrum of the aqueous medium containing silver nanoparticles showed absorption peak at around 430 nm. Fourier transform infrared spectra had shown that the biomolecule compounds were responsible for the reduction and capping material of silver nanoparticles. XRD study showed the particles to be crystalline in nature, with a face-centered cubic (fcc) structure. The size and stability were detected using DLS and zeta potential analysis. The antibacterial activity of AgNPs against generally found bacteria was assessed to find their potential use in silver-containing antibacterial product.

“…No disruption was seen in untreated cells, clearly indicating the enhanced antibacterial activity of AgNPs ( Figure 6A-C). The results from colony counting method showed that the AgNPs significantly reduced the number of E. coli cells from 10 6 to 1.3±0.9 CFUs/mL, while the of AgNPs compared with equivalent amounts of AgNO 3 . It has been reported that AgNPs show higher activity then their AgNO 3 counterparts.…”

“…1 Metal nanoparticles like silver, gold, and copper have been used for diagnosis and treatment of disease because of their catalytic, optical, electronic, antimicrobial, and magnetic properties. 2 Silver nanoparticles (AgNPs) are generally synthesized by physical and chemical methods such as electrochemical reduction and thermal evaporation, [3][4][5] but these methods are time-consuming and difficult to scale up. Furthermore, these methods are environmentally unsafe due to the use of toxic chemicals.…”

We report on the antimicrobial activity of a cream formulation of silver nanoparticles (AgNPs), biosynthesized using Withania somnifera extract. Aqueous extracts of leaves promoted efficient green synthesis of AgNPs compared to fruits and root extracts of W. somnifera . Biosynthesized AgNPs were characterized for their size and shape by physical-chemical techniques such as UV-visible spectroscopy, laser Doppler anemometry, transmission electron microscopy, scanning electron microscopy, atomic force microscopy, X-ray diffraction, and X-ray energy dispersive spectroscopy. After confirming the antimicrobial potential of AgNPs, they were incorporated into a cream. Cream formulations of AgNPs and AgNO 3 were prepared and compared for their antimicrobial activity against human pathogens ( Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Escherichia coli , and Candida albicans ) and a plant pathogen ( Agrobacterium tumefaciens ). Our results show that AgNP creams possess significantly higher antimicrobial activity against the tested organisms.

“…3 Therefore, the green synthesis of stable AgNPs with controlled size and shape is a very lucrative approach. As a result, some novel methods have recently been developed using either microbes (such as bacteria and fungi) 9,10 or plant extracts (from seeds, leaves, and tubers) [11][12][13] for the synthesis of AgNPs. The use of plants for AgNPs synthesis is preferred over other biological processes for several reasons: 1) it is less expensive, 2) it could be suitably scaled up for large-scale NP synthesis, 3) it avoids the elaborate process of maintaining a cell culture, 14 and 4) plant extracts possess many antioxidants, which act as reducing as well as capping agents.…”

Background The growing threat of microbial resistance against traditional antibiotics has prompted the development of several antimicrobial nanoparticles (NPs), including silver NPs (AgNPs). In this article, a simple and eco-friendly method for the synthesis of AgNPs using the cranberry powder aqueous extract is reported. Materials and methods Cranberry powder aqueous extracts (0.2%, 0.5%, and 0.8% w/v) were allowed to interact for 24 hours with a silver nitrate solution (10 mM) at 30°C at a ratio of 1:10. The formation of AgNPs was confirmed by ultraviolet-visible spectroscopy and their concentrations were determined using atomic absorption spectroscopy. The prepared NPs were evaluated by transmission electron microscopy, measurement of ζ-potential, and Fourier-transform infrared spectroscopy. The in vitro antimicrobial properties of AgNPs were then investigated against several microbial strains. Finally, in vivo appraisal of both wound-healing and antimicrobial properties of either plain AgNPs (prepared using 0.2% extract) or AgNP-Pluronic F-127 gel was conducted in a rat model after induction of a Staphylococcus aureus ATCC 6538P wound infection. Results The formation of AgNPs was confirmed by ultraviolet-visible spectroscopy, where a surface-plasmon resonance absorption peak was observed between 432 and 438 nm. Both size and concentration of the formed AgNPs increased with increasing concentration of the extracts. The developed NPs were stable, almost spherical, and polydisperse, with a size range of 1.4–8.6 nm. The negative ζ-potential values, as well as Fourier-transform infrared spectroscopy analysis, indicated the presence of a capping agent adsorbed onto the surface of the particles. In vitro antimicrobial evaluation revealed a size-dependent activity of the AgNPs against the tested organisms. Finally, AgNPs prepared using 0.2% extract exhibited a substantial in vivo healing potential for full-thickness excision wounds in rats. Conclusion AgNPs were successfully synthesized from a silver nitrate solution through a simple green route, using cranberry powder aqueous extract as a reducing as well as capping agent.
