Nowadays plant mediated synthesis of nanoparticles has great interest and achievement due to its eco-benign and low time consuming properties. In this study silver nanoparticles were successfully synthesized by using Morinda tinctoria leaf extract under different pH. The aqueous leaf extract was added to silver nitrate solution; the color of the reaction medium was changed from pale yellow to b...

In this experiment, green-synthesized silver and gold nanoparticles were produced rapidly by treating silver and gold ions with an extract of Memecylon umbellatum leaf. The reaction process was simple and easy to handle, and was monitored using ultraviolet-visible spectroscopy. The effect of the phytochemicals present in M. umbellatum, including saponins, phenolic compounds, phytosterols, and q...

The development of the biological synthesis of nanoparticles using microorganisms or plant extracts plays an important role in the field of nanotechnology as it is environmentally friendly and does not involve any harmful chemicals. In this study, the synthesis of silver nanoparticles using the leaves extract of Chinese tea from Camellia sinensis is reported. The synthesized nanoparticles were ...

In present study we used five green plants for microwave assisted synthesis of Alumina nanoparticles from Aluminum nitrate. Structural characterization was studied using x-ray diffraction that showed semi- crystalline and possibly, amorphous structure. Fourier infrared spectroscopy was used to determine Al-O bond and functional groups responsible for synthesis of nanoparticles. FTIR confirmed e...

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...

the synthesis of nanoparticles from biological processes is evolving a new era of research interests in nanotechnology. the aim of this study was to determined antibacterial activity of silver nanoparticles produced by rosmarinus officinalis l leaf extract against some human pathogenic bacteria. the formation and characterisation of agnps were confirmed by uv-vis spectroscopy, energy-dispersive...

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...
