Nanoparticles usage are now emerging as hazardous nanopollutants due to inappropriate usage and improper disposal. Superparamagnetic Iron Oxide Nanoparticles (SPIONs) is a widely used nanoparticle with various applications. In this study, SPIONs was evaluated for its impact against Vigna radiata and Eudrilus eugeniae. SPIONs were synthesized by chemical co-precipitation method in presence of cobalt chloride. The produced SPIONs was characterized using UV-Visible Spectroscopy, SEM (Scanning electron microscopy), EDX (Energy dispersive X-ray spectroscopy), XRD (X-ray diffraction), TEM (Transmission electron microscopy), AFM (Atomic force microscopy), XPS (X-ray photoelectron spectroscopy) and Zeta potential. The synthesized SPIONs were crystalline and monodispersed with size ranging between 15 nm and 20 nm. The seedlings of SPIONs treated Vigna radiata were found to have reduced root and shoot growth. The bioaccumulation of iron oxide in the treated plants was confirmed by ICP-OES (Inductively coupled plasma -optical emission spectrometry) analysis and Prussian blue staining. Cellular destruction and reduced reproduction rate were found in SPIONs exposed Eudrilus eugeniae and ICP-OES analysis of earthworm samples affirmed the bioaccumulation of SPIONs.

“…Among the various types of NPs, silver nanoparticles (AgNPs) are one of the most commercialized, comprising over 50% of global nanomaterial-based market products available in 2015 [2]. AgNPs are used widely due to their unique antimicrobial, optical, electromagnetic, and physicochemical properties [3]. The synthesis of NPs is dependent upon chemicalor physical-based methods that are expensive and require harmful chemicals despite their efficiency [4].…”

“…Although plant extracts have been widely used for nanoparticle synthesis [15], only a few studies have investigated the synthesis of AgNPs using living plants. In comparison to the production of NPs using plant extracts, living plants can reduce the spillover of toxic chemicals into the environment [3]. Thus, living plants are promising resources for nanoparticle synthesis that can meet the growing market demand for nanoparticle production.…”

Exogenous Production of Silver Nanoparticles by Tephrosia apollinea Living Plants under Drought Stress and Their Antimicrobial Activities

Nanoparticle (NP) synthesis by biological systems is more cost-effective, safe, and environmentally friendly when compared to currently used chemical and physical methods. Although many studies have utilized different plant extracts to synthesize NPs, few studies have incorporated living plants. In this study, silver nanoparticles (AgNPs) were synthesized exogenously by Tephrosia apollinea living plant system under the combined stresses of silver nitrate and different levels of drought stress simulated by Polyethylene glycol (PEG) (0, −0.1, −0.2, and −0.4 MPa for three and six days). Biomass, cell death, and H 2 O 2 content were evaluated to determine the toxicological effect of the treatments on the plant. More severe effects were detected in day 6 plants compared to day 3 plants, and at higher drought levels. UV-visible spectrum, energy dispersive X-ray spectroscopy, X-ray diffraction, scanning electron microscope, and Fourier transform infrared spectroscopy were used to detect and characterize the T. apollinea synthesized NPs. The shapes of the NPs were spherical and cubic with different phytochemicals being the possible capping agents. Broth microdilution was used to determine the antimicrobial activity of the NPs against Escherichia coli and Staphylococcus aureus. In this case, antimicrobial activity increased at higher PEG concentrations. Bactericidal effects were observed against E. coli, while only bacteriostatic effects were detected against S. aureus.

“…Furthermore, silver nanoparticles have been synthesized from the methanolic leaf extract of Eucalyptus as well (Dubey et al, 2009). In addition, mung bean seedlings have successfully absorbed silver ions f rom the soil and converted it into silver nanoparticles (Kumari et al, 2017). Plant extracts from different plant parts have been involved in production of silver nanoparticles like vegetative organs of some gymnosperms e.g.…”

A m e l Ta h a E m a n A f k a r A m a l F. A b d e l k a d e rThe in vivo bios ynthesis of antibacterial silver nanoparticles using red pepper (Capsicum annuum L) fruit extract ABSTRACT:Green synthesis of metal nanoparticles using green plants and microorganisms is a recent scientific approach that is being used by a wide range of industrial sections; including pharmaceutical, agricultural and medical. In the current research work we have been synthesized silver nanoparticles (AgNPs) using aqueous extract of red pepper sweet fruits of (Capsicum annuum L) belongs to the family solanaceae.The produced silver nanoparticles(AgNPs) showed a characteristic beak signal at 415 nm by using UV-Vis spectrophotometry. FTIR spectroscopy is used to detect the water-soluble molecules of red pepper fruit that were responsible for the reduction of silver ions. The crystalline nature and particle size of AgNPs is characterized using X-ray diffraction according to the line width of the plane; the refraction peak is calculated using the Scherrer's equation. Elemental analysis of the formed silver nanoparticles exhibited a strong peak signal at 3 KV; indicating the presence of silver nanoparticles.The produced silver nanoparticles were examined by scanning electron microscopy (SEM to picture the fine biosynthesized nanoparticles of silver. The biosynthesized AgNPs had inhibitory effect against Escherichia coli, Pseudomonas aeruginosa and Aramco S4 bacterial isolate with inhibition zones of 2 to 3 mm in diameter.
