"A Review of Plant-Based Green Nanoparticle Synthesis: Mechanisms, Metals, and Applications in Nanotechnology"

The green synthesis of nanoparticles offer promising applications across environmental and biomedical fields by reducing reliance on toxic chemicals. This approach, particularly through the use of plant materials, presents a safer alternative for nanoparticle production. Plants possess inherent reducing and capping agents, which aid in the synthesis process. This paper reviews the principles of green chemistry and explores the recent advancements in plant-mediated nanoparticle synthesis, discussing the various metals involved, including gold, silver, zinc, titanium, and palladium. Traditional physical and chemical synthesis methods, while effective, are often costly and hazardous. In contrast, plant-based green synthesis is an eco-friendly alternative, involving mechanisms such as reduction, stabilization, nucleation, aggregation, and capping, followed by characterization. The rise of green nanotechnology highlights the potential for sustainable, safer, and less toxic solutions for diverse applications, ranging from biosensors and biomedicine to catalysis, electronics, and antibacterial technologies. This approach opens new avenues for the design of novel nanoparticles with desirable properties for various scientific and industrial uses.
