Phyto-Nanotechnology: Engineering the Future of Precision Agriculture and Environmental Remediation

Abstract

The intersection of nanotechnology and plant biology—phyto-nanotechnology—has emerged as a transformative discipline in 2024–2026. This paper explores the "green synthesis" of metallic nanoparticles (Ag, Au, ZnO) using plant extracts as reducing and stabilizing agents, emphasizing the biochemical pathways involved. We analyze the dual role of nanomaterials: first, as "smart" delivery systems for fertilizers and pesticides (nano-encapsulation) to minimize environmental leaching; and second, as agents for phytoremediation, where nanoparticles enhance the sequestration of heavy metals from contaminated soils. This expansion delves into the "Nano-Bio Interface," examining how nanoparticle surface charges influence cellular uptake via endocytosis and the subsequent impact on the plant's antioxidant defense systems. The paper further discusses the physiological impact of carbon nanotubes and quantum dots on plant photosynthesis and the ethical considerations of nanotoxicity in the food chain.
