“…In recent years, synthesis of nanoparticles by using plants is gaining importance due to its effortlessness and eco-friendless [11]- [13]. Recently the biological synthesis of gold nanoparticles using many spices such as black seed (Nigella sativa), garlic, curcumin, Cinnamomum zeylanicum and clove (Syzygium aromaticum) has been reported [14]- [23].…”

In this investigation, the anticancer potentiality and biological mechanism of gold nanoparticles (AuNPs) was studied in SUDHL-4 cell line. Metallic AuNPs were prepared and stabilized with ethanol clove (Syzygium aromaticum) extract. The green synthesis of AuNPs was characterized and evaluated by UV-Visible Spectroscopic, X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Transmission electron microscopy (TEM), Dynamic Light Scattering (DLS) and biological activities using various biochemical assays. Green synthesis of AuNPs was confirmed by instrument method. The TEM images show polydisperse, mostly spherical AuNPs particles of 12 -20 nm. AuNPs were decreased the growth and viability of SU-DHL-4 cell line and increased the apoptosis. The treatments of SU-DHL-4 cells with AuNPs resulted in a moderate considerably increase in Reactive oxygen species (ROS) production. We measured apoptosis by Annexin-V/propidium iodide (PI) in the existence and nonexistence of the antioxidant N-acetyl-Lcysteine (NAC), the glutathione-depleting agent buthionine sulfoximine (BSO), or caspase inhibitors to determine the mechanism of cell death. AuNPs are unique potential anticancer agents that cause ROS-dependent apoptosis in SUDHL-4 cell line which was improved by depletion of glutathione (GHS) and inhibited by N-acetyl-L-cysteine on Z-VAD-FMK.

“…Phytoremediation (Rasico and Navari-Izzo 2011;Ali et al 2013) and phytomining (Sheoran et al 2009) are the most important areas of application of these plants. However, the recent studies have suggested a possibility of their use in green nanotechnology (Nath and Banerjee 2013). Approximately 500 taxa have been reported as hyperaccumulators with almost 90 % of known species being endemic to metalliferous soils, such as serpentine soils (Van der Ent et al 2013).…”

A vulnerable point of the currently used approach to the search for the new species capable of abnormal accumulation (hyperaccumulation) of trace elements is that most studies have been conducted in laboratory conditions and focused on the determination of a limited number of elements. We propose a methodology that enables screening for multi-element accumulating plants. This methodology is based on two analytical steps: a semiquantitative analysis mode by ICP-MS that allows selection of plant samples which are enriched in one or more trace elements, and a quantitative analysis necessary for confirmation of the results derived from the first step. The proposed methodology was tested in the study of 30 plant samples. Ten elements with the highest concentrations obtained in the semiquantitative analyses were determined quantitatively with the following detection limits (in mg/kg): 0.001 for Ag, 0.08 for Ba, 0.002 for Cd, 0.005 for Co, 0.01 for Cr, 0.003 for Cu, 1.4 for Fe, 0.012 for Mn, 0.03 for Ni, 0.006 for Pb, 0.001 for Sc, 0.001 for Tl and 0.06 for Zn. The CRM recovery values obtained were in the range of 80-103 %, and the precision of the measurements (as RSD) was in the range of 0.34-4.05 %. We also propose a simple method for evaluation of typical element concentrations in plants collected for analyses. Our approach provides a novel screening method for both identification of new hyperaccumulators and for studying a larger number of elements accumulated by plants. This method may find its application in environmental biotechnology.

“…Biological synthesis involves biochemical conversion of a substrate, whereas the chemical one is based on the reduction of chemical compounds. The formation of NPs by physical and chemical routes requires toxic chemicals which results in toxic side effects [6]. Green synthesis also provides the cost effective, non-toxic, large-scale, and high-output nanoparticle products [13].…”

The effect of biologically and chemically synthesized silver nanoparticles (AgNPs) on biofilm formation

et al. 2017

Abstract. Bionanotechnology has emerged up as integration between biotechnology and nanotechnology for developing biosynthetic and environmental-friendly technology for synthesis of nanomaterials. Different types of nanomaterials like copper, zinc, titanium, magnesium, gold, and silver have applied in the various industries but silver nanoparticles have proved to be most effective against bacteria, viruses and eukaryotic microorganisms. The antimicrobial property of silver nanoparticles are widely known. Due to strong antibacterial property silver nanoparticles are used, e.g. in clothing, food industry, sunscreens, cosmetics and many household and environmental appliances. The aim of the study was to compare the effect of silver nanoparticles (AgNPs) synthesized biologically and chemically on the biofilm formation. The biofilm was formed by the bacteria isolated from the water supply network. The commonly used crystal violet assay (CV) was applied for biofilm analysis. In this study effect of biologically synthesized Ag-NPs on the biofilm formation was evaluated.
