EVALUATING THE IMPACT OF U. TOMENTOSA LEAF-EXTRACTED MAGNETITE NANOPARTICLES ON GREEN PEACH APHID

Abstract

Magnetite (Fe3O4) nanoparticles have gained significant attention due to their diverse applications in various fields, including biomedicine, agriculture, and diagnostics. The tunable properties of these nanoparticles make them suitable for targeted drug delivery, cancer diagnostics, magnetic resonance imaging, catalysts, pharmaceuticals, and more. Several synthesis methods have been developed to prepare magnetite nanoparticles, but many of these methods involve purification steps, hazardous by-products, and high-temperature conditions. In response to these limitations, researchers have turned to environmentally friendly and cost-effective "green" synthesis routes using plant extracts. In this study, we explored the synthesis of magnetite nanoparticles (Fe3O4NPs) through a green approach, utilizing the aqueous extract of Urtica tomentosa leaves. This method provides an eco-friendly, cost-effective, and non-toxic alternative to traditional synthesis routes. The magnetite nanoparticles obtained through this green synthesis route were characterized for their potential impact on green peach aphids. The use of magnetite nanoparticles in pest control is a novel and innovative approach. These nanoparticles have shown promise in various applications, but their effects on pests like green peach aphids remain relatively unexplored. The current study addresses this gap by investigating the influence of Fe3O4NPs on green peach aphid populations.
