“…Nevertheless, these nanoparticles are less toxic to most common mammalian cells (Chinese hamster ovary [CHO] cells) up to 300±18.29 µg/mL. Similar findings were noticed when AgNPs synthesized with leaf extract of Sesbania grandiflora and rhizome extract of Acorus calamus demonstrated to be cytotoxic to MCF-7 and A431 carcinoma cells, respectively [23,24]. Biologically synthesized AgNPs showed high inhibitory effect against various cancer cell lines at higher concentration.…”

Objective: We aimed to synthesize the cost effective, one pot and an eco-friendly technique for the green synthesis of silver nanoparticles (AgNPs) using 1 mM of silver nitrate (AgNO 3 ) solution through the aqueous leaf extracts of Gloriosa superba (GS) reducing and capping agent and its anticancer activity.Methods: Synthesis briefly 95 mL of 1 mM AgNO 3 was taken into amber colored conical flask and added 5 mL of aqueous leaf extract of GS (pale brown) and incubated at room temperature in dark condition for about 24 hrs. Characterization of AgNPs derived from GS (GS-AgNPs) was performed with physiochemical techniques (ultraviolet, transmission electron microscope [TEM], X-ray diffraction [XRD], and thermal gravimetric analysis) and cytotoxicity by 3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyltetrazolium bromide assay. Results:We synthesized cost effective, eco-friendly AgNPs were characterized by physiochemical techniques. The crystal nature of AgNP was studied by XRD. TEM studies reveal the morphology of GS-AgNPs, the size of the nanoparticle is 10-50 nm. The cytotoxicity of GS-AgNPs studied against the four human cancerous cell line DU145, SKOV3, PC3, and A549 but the GS-AgNPs are most sensitive toward the SKOV3 cell line. The minimum inhibitory concentration (IC) is 79. 45±5.26, 61.80±4.27, 94.74±9.26, and 90.10±8.24 µg/mL, respectively. Morphological assessment of the SKOV3 cells was studied using AO/EB and Hoechst staining at IC 50 concentration. Conclusion:The bio fabrication of the GS-AgNPs were simple, eco-friendly and one pot synthesis, it is used as an anticancer agent in future, pending further investigation.

“…Figure 8 shows the energy dispersive spectrum of the synthesized nanoparticles, which suggests the presence of silver as the ingredient element. Metallic silver nanoparticles generally show a typically strong signal peak at 3 keV, due to surface plasmon resonance (Magudapatty et al 2001;Kaviya et al 2011;Das et al 2013). Figure 8 shows the quantitative information of biosynthesized AgNPs.…”

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.

“…Wide varieties of methods have been reported for synthesis of zinc oxide and iron oxide nanoparticles such as coprecipitation technique [2], thermal decomposition methods [3], hydrothermal technique [4], sol gel method [5], and electrochemical methods [6]. However these methods are energy consuming, using hazardous solvents and expensive reagents in their preparation [7,8]; therefore the rising needs to develop eco-friendly green method for nanoparticle preparation [9]. Recently plant mediated green synthesis of different nanoparticles from various plants such as Cassia alata [10], Camellia sinensis [11], Mangifera indica [12], Azadirachta indica [13], Syzygium cumini [14], and Ocimum basilicum [15] has been reported.…”

The objectives of this present study are to synthesize iron oxide and zinc oxide nanoparticles from different concentrations of Sesbania grandiflora leaf extract (5-20%) using zinc nitrate and ferrous chloride as precursor materials and synthesized nanoparticles were characterized using UV-visible spectrometer, FTIR, X-ray diffraction, and SEM. The results showed that synthesized zinc oxide and iron oxide nanoparticles exhibited UV-visible absorption peaks at 235 nm and 220 nm, respectively, which indicated that both nanoparticles were photosensitive and the XRD study confirmed that both nanoparticles were crystalline in nature. In addition, FTIR was also used to analyze the various functional groups present in the synthesized nanoparticles. The SEM results reveal that zinc oxide nanoparticles were spherical in shape and having the particle size range of 15 to 35 nm whereas the iron oxide nanoparticles were nonspherical in shape with the size range of 25 to 60 nm. Application of synthesized nanoparticle on seafood effluent treatment was studied.
