Abstract
Plant nanobionics is an innovative interdisciplinary approach which integrates engineered nanoparticles into plant systems to enhance their natural functionalities and enable novel capabilities. This paper explores the potential of nanoparticles to improve photosynthetic efficiency, nutrient uptake, and increase plant resilience against environmental stressors. Enhancing carbon fixation with functionalized silica nanoparticles, reducing photoinhibition with cerium oxide nanoparticles, and broadening the light absorption spectrum with nanomaterials such as carbon nanotubes (CNTs) and quantum dots are some of the main uses of plant nanobionics. These advancements offer solutions to fundamental limitations in photosynthesis, including suboptimal light ustilization, restricted carbon dioxide availability, and oxidative stress.
Nanoparticles also revolutionize nutrient management through innovations such as nanofertilizers and chelated metal nanoparticles. These technologies enhance nutrient bioavailability, minimize environmental impacts, and improve plant growth in nutrient-deficient soils. For example, zinc oxide and iron oxide nanoparticles encourage the effective delivery and uptake of nutrients, while titanium dioxide and carbon-based nanomaterials contribute to soil remediation by immobilizing heavy metals and improving soil health.
Nanotechnology in agriculture offers transformative benefits such as increased crop yields, sustainable resources management, and climate change mitigation. However, challenges such as environmental safety, scalability, and regulatory considerations must be addressed to ensure responsible application. This study highlights the role of plant nanobionics in advancing agricultural productivity and sustainability, emphasizing its potential to address global challenges such as food security and environmental conservation.
