Green synthesis of nanoparticles, as fundamental building blocks of nanotechnology, has recently attracted considerable attention. Silver nanoparticles have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications. In the present paper we report our research results on biosynthesis of silver nanoparticles from silver precursor usin...

In the present study, we have reported the biological synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (PBW343, Triticum durum and Aegilops tauschii )for the reduction of silver ions to silver nanoparticles. Bioreduction of Ag+ to Ag0 was observed when aqueous extract augmented with silver nitrate (AgNO3) was incubated ...

Biological synthesis of nanoparticles is a relatively new emerging field of nanotechnology which has economic and eco-friendly benefits over chemical and physical processes of synthesis. In the present work, for the first time, the brown marine algae Sargassum muticum (S. muticum) aqueous extract was used as a reducing agent for the synthesis of nanostructure silver particles (Ag-NPs). Structur...

Silver nanoparticles (Ag-NPs), the most popular nanoparticles, possess unique properties. Achillea biebersteinii is a plant of the Asteraceae family rich in active antitumor components. The aim of this research was the characterization and investigation of the cytotoxic properties of Ag-NPs synthesized using A. biebersteinii flower extract, on a human breast cancer cell line. The Ag-NPs were sy...

The use of less hazardous chemicals or natural material in place of toxic chemical for the formation of metal nanoparticle is known as green synthesis. The present paper deals with greener approach for the synthesis of silver (Ag) nanoparticles. The Saraca asoca plant leaves extract solution was used for the silver nanoparticles. Confirmation of Ag nanoparticles has been done using var...

Generally, limited research is extended in studying stability and applicational properties of silver nanoparticles (Ag NPs) synthesized by adopting 'green chemistry' protocol. In this work, we report on the synthesis of stable Ag NPs using plant-derived materials such as leaf extract of Neem (Azadirachta indica) and biopolymer pectin from apple peel. In addition, the applicational properties of...

For the first time the extract of the plant of Tilia platyphyllos was used to green synthesis of Ag nanoparticles (NPs) supported on Ziziphus jujuba kernel as an environmentally benign support. Ag NPs/ Ziziphus  jujuba  kernelas  an  effective  catalyst  was  prepared  through reduction  of Ag+ions using Tilia  platyphyllos extractas  the  reducing  and capping agent  and Ag  NPs immobilization...

In the present work, we describe a simple, cheap, and unexplored method for "green" synthesis of silver nanoparticles using cell extracts of the cyanobacterium Anabaena doliolum. An attempt was also made to test the antimicrobial and antitumor activities of the synthesized nanoparticles. Analytical techniques, namely UV-vis spectroscopy, X-ray diffraction, Fourier transform infrared (FTIR) spec...

Illicium verum Hooker fillius or commonly called star anise is a member of Magnoliaceae. The synthesis of metal nanoparticles is a growing area for research due to its potentiality in the application and development of advanced technologies. In general, nanoparticles are synthesized by using chemical methods which are not eco-friendly. Here, we have used a fast, convenient and environment-frien...

Within this study, a stable nanosuspension of silver nanoparticles (Ag NPs) was prepared using a two-step synthesis and stabilization approach. The Ag NPs were synthesized from a silver nitrate solution using the Origanum vulgare L. plant extract as the reducing agent. The formation of nanoparticles was finished upon 15 min, and subsequently, stabilization by polyvinylpyrrolidone (PVP) using we...
