Opis:
Biological synthesis of metal nanoparticles gained worldwide interest due to their rapid, non-toxic, economical, single-step technique and eco-friendly alternative. Green-chemical approach of production of Zinc Oxide (ZnO) nanoparticles (NPs) has been exploited in the field of medicine, food packaging, nano-optical and electrical devices. Muntingia calabura is a multipotent medicinal plant with astounded biological activities and phytoconstituents. The nanoparticles obtained using aqueous extracts of various parts of M. calabura were characterized with UV-VIS spectroscopy to obtain information concerning the optical properties of synthesized ZnO nanoparticles. The proposed green and economical method could be used for large scale production of nanostructures because of its advantages over other physical and chemical methods.

Opis:
Green synthesis of Zinc oxide nanoparticles (ZnO-NPs) is a novel and non-toxic method as compared to the hazardous conventional physical and chemical methods. Herein, we report production of ZnO-NPs for the first time using whole vegetative parts of Sesamum indicum L. The aqueous extracts of various parts of S. indicum were used to synthesize nanoparticles in this study. The synthesized nanoparticles were evaluated using UV-visible spectroscopy for confirmation and characterization. The maximum UV-visible spectral absorption peaks were observed from 293 to 296 nm wavelengths. Leaf and stem reaction mixtures exhibited the sharpest absorption peaks of all the variations at 293 nm and root at 296 nm. This study leads to the development of cost-effective ZnO-NPs synthesis with possible further exploration to serve mankind.

Opis:
The biogenesis of nanoparticles recently gained more attention. Here, we report the biogenesis of zinc oxide (ZnO) nanoparticles using aqueous extracts of the leaves, stem, root, flowers and fruits of Croton bonplandianum Baill. at room temperature. Croton bonplandianum is an important medicinal plant used to cure many pathological conditions in the traditional systems of Indian medicines due to the presence of important and specific bioactive compounds in the plant parts of this plant. Aqueous solution of Zinc Nitrate hexahydrate [Zn(NO3)2·6H2O] was used as a precursor and the various plant extracts played as reducing agents. The formation of ZnO nanoparticles was monitored by UV-Visible spectrophotometric analysis. The leaf extract showed strong absorbance peak at 302 nm, stem and fruit at 293 nm, root at 290 nm and flowers at 305 nm.
