Memecylon edule leaf extract mediated green synthesis of silver and gold nanoparticles
We used an aqueous leaf extract of Memecylon edule (Melastomataceae) to synthesize silver and gold nanoparticles. To our knowledge, this is the first report where M. edule leaf broth was found to be a suitable plant source for the green synthesis of silver and gold nanoparticles. On treatment of aqueous solutions of silver nitrate and chloroauric acid with M. edule leaf extract, stable silver a...
متن کاملPlant Extract Mediated Synthesis of Gold Nanoparticles: a Mini-review
Nanoparticles are an important field of research due to their unique properties as compared to their bulk structures and the diverse applications arising from these properties. The major synthesis methods available involve physical and chemical methods which are expensive and use toxic chemicals. There is hence a need for an eco-friendly synthesis route which is in par with the chemical methods...
متن کاملSynthesis of non-spherical gold nanoparticles
Non-spherical gold nanoparticles such as rods (short, long) (1,2), wires, cubes (3), nanocages (4), (multi-)concentric shells (5), triangular prisms (6-7), as well as other more exotic structures such as hollow tubes, capsules (6), even branched nanocrystals (8-9) have garnered significant research attention in the past few years. They exhibit unique and fine-tuned properties which either stron...
متن کاملOne-step green synthesis and characterization of leaf extract-mediated biocompatible silver and gold nanoparticles from Memecylon umbellatum
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...
متن کاملThe Synthesis of Gold Nanoparticles Using Amaranthus spinosus Leaf Extract and Study of Their Optical Properties
We report here the application of a medicinally important plant Amaranthus spinosus for the synthesis of gold nanoparticles (AuNPs). Different concentrations of ethanolic leaf extract of the plant were reacted with aqueous solution of HAuCl4·4H2O under mild reaction conditions. Synthesis of AuNPs was confirmed from the UV-Vis study of surface plasmon resonance property of the colloidal solution...
