Abstract

This research investigates the green synthesis of silver nanoparticles using Azadirachta indica (Neem) leaf extracts, focusing on the effects of key synthesis parameters—pH, temperature, and reaction time—on nanoparticle characteristics. The study aims to identify and characterize the specific plant metabolites responsible for nanoparticle formation and stabilization, providing insights into the biochemical interactions governing green synthesis. The experimental design involved the reduction of silver nitrate using aqueous leaf extracts of Azadirachta indica, with synthesis conditions optimized to study their impact on nanoparticle size, morphology, and stability. Key findings revealed that higher pH levels favored the formation of smaller, uniform nanoparticles, while temperature influenced their shape, with lower temperatures producing spherical particles. The stability of nanoparticles was optimal at reaction times of 30-35 minutes, and the highest yield was achieved at pH 8.0, 60°C, and 30 minutes. These findings address significant gaps in the literature regarding the specific biochemical interactions in green synthesis, providing a more predictable and controlled approach to nanoparticle production. The broader implications highlight the potential for scaling up green synthesis methods, offering sustainable and eco-friendly alternatives to conventional nanoparticle synthesis techniques, with applications across biomedicine, environmental science, and industrial sectors.
