The exploitation of various plant materials for the biosynthesis of nanoparticles is considered a green technology as it does not involve any harmful chemicals. The aim of this study was to develop a simple biological method for the synthesis of silver and gold nanoparticles using Chrysopogon zizanioides. To exploit various plant materials for the biosynthesis of nanoparticles was considered a ...

BACKGROUND Biosynthesis of nanoparticles using microorganisms, enzymes, and plant extracts is regarded as an alternative to chemical methods. Microalgae appear to be an efficient biological platform for nanoparticle synthesis as they grow rapidly and produce large biomass at lower cost. OBJECTIVES The possibility of silver nanoparticles biosynthesisby freshwater green microalgae, Chlamydomona...

BACKGROUND Development of an environmentally benign process for the synthesis of silver nanomaterials is an important aspect of current nanotechnology research. Among the 600 species of the genus Dioscorea, Dioscorea bulbifera has profound therapeutic applications due to its unique phytochemistry. In this paper, we report on the rapid synthesis of silver nanoparticles by reduction of aqueous Ag...

Surfactant capped uniform silver nanoparticles were synthesized by the chemical reduction reaction in a microemulsion media, which is formed under high shear mixing condition. Silver nitrate solution and 2-ethyl hexanol were taken as aqueous and organic phase, sodium borohydride was used as reducing agent and Span-80 (sorbitan monooleate) as the capping agent. Synthesized silver nanoparticles w...

To probe the nature of metal-catalysed processes and to design better metal-based catalysts, atomic scale understanding of catalytic processes is highly desirable. Here we use aberration-corrected environmental transmission electron microscopy to investigate the atomic scale processes of silver-based nanoparticles, which catalyse the oxidation of multi-wall carbon nanotubes. A direct semi-quant...

The metallic nanoparticles have great attention of Chemists, Physists, Biologists and Engineers who wish to use them for development of new generation nanodevices. In this present study silver nanoparticles were synthesized from aqueous silver nitrate (1mM) through a simple and ecofriendly route using leaf broth of Ocimum sanctum as reductant and stabilizer. The aqueous silver ions when exposed...

recently, biosynthesis of nanoparticles has received attention due to an increasing need of developing rapid, simple and ecofriendly protocol. pathogenicity of some of the organisms and lengthy reaction are the drawbacks involved with biosynthesis. we describe a simple protocol for rapid synthesis of silver nanoparticles through biological route using a marine-derived fungus aspergillus niger. ...

Silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. A simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  The present study aimed at the comparative study of silver nanopartic...
