Synthesis, characterization and biological investigation of zinc nanoparticles using Acacia modesta Wall. leaves.

The study aimed to synthesize zinc nanoparticles (Zn-NPs) using an aqueous extract derived from Acacia modesta Wall. leaves. Several characterization techniques were employed to confirm the successful formation of zinc nanoparticles.

Antimicrobial efficacy of phyto-synthesized silver nanoparticles using aqueous leaves extract of Rosamarinus officinalis L.

The current research investigation demonstrated that the aqueous leaves extract of Rosamarinus officinalis possesses cardinal phyto-chemicals to fabricate AgNPs in an eco-friendly way. The phyto-synthesized AgNPs were characterized to be stable, monodispersed, polycrystalline and mostly spheroidal in conformation. The nano-spheriods were observed to be 25-75 nm in diameter, displaying λ peak at 430 nm.

Phyto-fabrication, purification, characterisation, optimisation, and biological competence of nano-silver.

Published studies indicate that virtually any kind of botanical material can be exploited to make biocompatible, safe, and cost-effective silver nanoparticles. This hypothesis is supported by the fact that plants possess active bio-ingredients that function as powerful reducing and coating agents for Ag+. In this respect, a phytomediation method provides favourable monodisperse, crystalline, and spherical particles that can be easily purified by ultra-centrifugation.

Green synthesis, characterisation and biological evaluation of AgNPs using Agave americana, Mentha spicata and Mangifera indica aqueous leaves extract.

The current study was performed to synthesize stable, eco-friendly and bio-compatible silver nano-particles (AgNPs) of , and leaves and to screen them for biological activities. The ultraviolet-visible spectroscopic analysis revealed that λ-max for AgNPs range from 350-500 nm. All AgNPs possessed polycrystalline structure as notified as intense graphical peaks in complete spectrum of 20 values ranging from 10-80° in X-ray diffraction measurements and supported by scanning electron microscopy data.
