Abstract
En 中文
The study describes green synthesis of diverse nanoparticles using a single platform technology using water extract of powdered coffee and clove/polyphenols of coffee and clove under mild environmental conditions. Treatment of the respective chloride salt solutions/chloride salt combinations, with sodium bicarbonate (NaHCO3) in presence of polyphenolic plant extract yielded 6.5-26.8% nanoparticles of Mn, Zn, Cu, Co, Fe, Ni, and P, with diameters ranging from 1.0 to 99.7 nm. The nanoparticles were found to be stable for more than 15 days. Their potential in enhancing crop growth was also examined by treating pearl millet plants to foliar sprays of the synthesized nanoparticles. Green-synthesized Fe nanoparticles had a greater effect in enhancing the plant biomass when compared with commercially available Fe nanoparticles. The nanoparticle spray also did not affect the soil microflora adversely. The biological route to nanoparticle synthesis, utilizing indigenous plant products is a cost-effective approach, and their potential to be utilized as both reducing and stabilizing agents in the process offers a green platform for nanoparticle synthesis.
