“…Analysis of AgNPs through Energy dispersive X-ray (EDX) spectrometers confirmed the presence of elemental silver signal at 3 keV along (Fig. 2b) with other weak signals corresponding to oxygen and carbon, which could have essentially derived from the plant extract and consistent with previous studies [31,32]. FTIR measurement was carried out to identify the possible biomolecules in S. nigrum leaf extract responsible for capping leading to efficient stabilization of the silver nanoparticles (Fig.…”

Solanum nigrum, a medicinal plant, traditionally used in treating diabetes mellitus. In this study, we used the leaf extract of the plant to synthesize silver nanoparticles (AgNPs), as a proposition to treat alloxaninduced diabetic rats. The phytosynthesised AgNPs were analyzed using UV-visible and Fourier transform infra-red spectroscopy for their functional groups. Transmission electron microscopy revealed that, the synthesized particles are found to be 4-25 nm in size. Monodispersed and spherical nature of synthesized AgNPs were shown by scanning electron microscope and the presence of Ag in the AgNPs was confirmed by energy dispersive spectrum. The phytosynthesised AgNPs were evaluated for its antidiabetic activity in alloxan-induced diabetic rats. AgNPs-treated diabetic rats found to be significantly improved the dyslipidemic condition as seen in the diabetic control. Furthermore, it also reduced the blood glucose level over the period of treatment. The improvement in body weight was also found to be evidence for S. nigrum extract-mediated AgNPs as a potential antidiabetic agent against alloxaninduced diabetic rats.

“…Silver nitrate (AgNO 3 ) was purchased from Sigma-Aldrich (St Louis, MO, USA) and the synthesis of AgNPs was carried out according to Lee et al 8 Briefly, 4 mL of the extract was mixed with 96 mL of 1 mM AgNO 3 solution and the resulting greenish white mixture was incubated for 8 hours in a rotary shaker (200 rpm) at 26°C. The reduction of Ag + ions to Ag nanocrystals was monitored by the change in the color of the reaction mixture from greenish white to dark brown.…”

“…Several studies reported AgNPs synthesis using biological materials, such as microorganisms, plant extracts, milk, and panchakavya. [7][8][9][10] Phytosynthesis of AgNPs using plant materials has an edge over microbial mediated synthesis owing to their immediate and large-scale production. 11,12 Thus, considerable attention is given to exploit the…”

A rapid, green phytosynthesis of silver nanoparticles (AgNPs) using the aqueous extract of Helianthus tuberosus (sunroot tuber) was reported in this study. The morphology of the AgNPs was determined by transmission electron microscopy (TEM). Scanning electron microscopy–energy-dispersive spectroscopy (SEM–EDS) and X-ray powder diffraction (XRD) analysis confirmed the presence of AgNPs. Fourier transform infrared spectroscopy (FTIR) analysis revealed that biomolecules in the tuber extract were involved in the reduction and capping of AgNPs. The energy-dispersive spectroscopy (EDS) analysis of the AgNPs, using an energy range of 2–4 keV, confirmed the presence of elemental silver without any contamination. Further, the synthesized AgNPs were evaluated against phytopathogens such as Ralstonia solanacearum and Xanthomonas axonopodis . The AgNPs (1–4 mM) extensively reduced the growth rate of the phytopathogens. In addition, the cytotoxic effect of the synthesized AgNPs was analyzed using rat splenocytes. The cell viability was decreased according to the increasing concentration of AgNPs and 67% of cell death was observed at 100 μg/mL.

Nanoagrochemicals, such as nanopesticides, nanofertilizers or plant growth stimulating nanosystems, were primarily designed to increase solubility, enhance bioavailability, targeted delivery, controlled release and/or protection against degradation resulting in the reduced amount of applied active ingredients and finally in a decrease of dose-dependent toxicity/burden. This paper is a comprehensive up-to-date review related to the preparation and the biological activity of nanoformulations enabling gradual release of active ingredient into weeds and the body of pests and controlled release of nutrients to plants. The attention is also devoted to the decrease of direct environmental burden and economic benefits due to application of nanoformulations, where less amount of active ingredient is needed to achieve the same biological effect in comparison with bulk. The application of nanotechnology in the areas such as food packaging, food security, encapsulation of nutrients and development of new functional products is analysed. The use of nanoparticles in biosensors for detection of pathogens and contaminants as well as in DNA and gene delivery is discussed as well. Benefits and health risks of nanoagrochemicals are highlighted, and special attention is given to nanoecotoxicology and guidelines and regulatory documents related to the use of nanoformulations in agriculture and food industry.
