The effects of five nanomaterials (multiwalled carbon nanotubes [MWCNTs], Ag, Cu, ZnO, Si) and their corresponding bulk counterparts on seed germination, root elongation, and biomass of Cucurbita pepo (zucchini) were investigated. The plants were grown in hydroponic solutions amended with nanoparticles or bulk material suspensions at 1000 mg/L. Seed germination was unaffected by any of the trea...

Water-soluble Ag-Au bimetallic nanostructures were prepared via co-reduction and seed-mediated growth routes employing poly-(4-styrenesulfonic acid-co-maleic acid) (PSSMA) as both a reductant and a stabilizer. Ag-Au alloy nanoparticles were obtained by the co-reduction of AgNO3 and HAuCl4, while Ag-Au core-shell nanostructures were prepared through seed-mediated growth using PSSMA-Au nanopartic...

Bimetallic nanoparticles have emerged up as advanced nanomaterials due to the synergism between two metallic nanoparticles in core-shell or alloy arrangement. Moreover, bioinspired synthesis of nanoparticles is an evergreen approach of nanobiosciences. In this experiment, we have fabricated silver, gold and silver (core) gold (shell) bimetallic nanoparticles using leaf extract of Catharanthus r...

background the production of nanoparticles using a biosystem is considered green chemistry. application of plant extracts as a biological process has been proven to be suitable for synthesis of nanoparticles. objectives this study designed in order to evaluate the production of silver nanoparticles using juglans regia leaf extract and to compare the outcome of different preparation methods of p...

The objective of the study was to characterize silver nanoparticles (Ag-NPs) and their bioactivities in early tracheophytes (Pteridophyta). Aqueous leaf extract of a critically endangered fern, Pteris tripartita Sw., was used for one-step green synthesis of Ag-NPs. The biosynthesized Ag-NPs were characterized using ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, scann...

The present study shows the synthesis of silver nanoparticles (Ag NPs) using a methanolic and aqueous extract R. stricta. UV–visible spectroscopy, energy-dispersive X-ray diffraction (EDX), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR) techniques were used to further characterize Ag NPs. spectra give surface Plasmon resonance (SPR) at 490–56...

Silver (Ag) nanoparticles were produced using DNA extracted from salmon milt as templates. Particles spherical in shape with an average diameter smaller than 10 nm were obtained. The nanoparticles consisted of Ag as the core with an outermost thin layer of DNA. The DNA/Ag hybrid nanoparticles were immobilized over the surface of cotton based fabrics and their antibacterial efficiency was evalua...

Ag-Au alloy nanoparticles with tunable shape and composition were prepared by a replacement reaction between Ag nanoparticles and chloroauric acid at one hundred and fifty degree celsius temperature under oilbath heating. The replacement reaction between silver nanostructures and chloroauric acid solution has recently been demonstrated as a versatile method for generating Au-Ag alloy nanostruct...
