Green Synthesis of MgO Nanoparticles from Eicchornia crassipes Aqueous Leaf Extract and its Phytotoxic Effect on Triticum aestivum

Abstract

Nano-biotechnology has a profound impact on various fields. The photo-mediated green approach of structuring the oxide nanoparticlesfrom metal has become exigent due to helping to circumvent the adverse effects on the environment as compared to other methods ofsynthesis like chemical and physical. For synthesis of Nano-composites by plant material was initiated due to the material containing anenormous number of bio-reductants and surfactants, useful formation of nanoparticles. The formation of phytofacile metal nanoparticlesis due to the presence of phyto-components which an efficacious substitutes as bio-reductants and surfactants. The green synthesis of MgO2 is eco-friendly towards the creation of inorganic metal oxide nanoparticles. The magnesium oxide metal nanoparticles act as a verystable and safest component of the human body. In the present work, the preparation of magnesium oxide nanoparticles (MgO2NPs) wasinitiated by using an aqueous leaf extract of Eicchornia crassipes. The synthesized MgO2 nano-composites were characterized through UV–vis spectroscopy. The nanoparticles showed absorbance at 314 nm. The phytotoxicity of synthesized MgO2 NPs was tested againstthe Triticum aestivum. The results indicate that increase in all aspects of essential components exposed to the MgO2 nanoparticles incomparison to the control treatment which showed better content for root and shoot growth of the T. aestivum. This is a fruitful outcomeof this research work that the exposure of nanoparticles to T. aestivum leads to grow the plant vigorously and did not show any adverseeffect. This claimed that the MgO2 NPs are eco-friendly for the environment.
