Exploring Silicon Nanoparticle Uptake, Transport, and Biological Functions in Plants

Nanoparticles (NPs) show a potential to greatly improve the efficacy of agrochemicals, crop yield, and soil vitality. Nevertheless, scientists have yet to understand the mechanisms by which nanoparticles enter plants, plant cells, and organelles. To improve our understanding of nanoparticle-plant interactions, our primary focus is on elucidating the mechanisms by which nanoparticles transpose barriers within plants and plant cells and identifying the key factors that impede an effective dispersion of nanoparticles. Silicon (Si) is a highly beneficial metalloid found in nature and positively mitigates environmental problems. The exceptional chemical and optoelectronic characteristics of silicon/silica nanoparticles (Si/SiO2 NPs) have come to significant attention. Researchers have found its mesoporous structure, easy availability, and minimal biological toxicity. Chemical, physical, and biological processes can be used to create Si/SiO2 NPs, which can then be applied to leaves, the soil, or seed priming. After Si/SiO2 NPs are ingested and transported to target cells, they experience optimal growth, development, and resistance to environmental stressors, pest attacks, and pathogen infections. Si/SiO2 NPs may be used as environmentally benign and economical supplements for sustainable agriculture. It facilitates the uptake of nutrients, increases plant resilience, and helps plants to manage biotic stress. This study suggests developing nanomaterials for agriculture to increase plant yields and stress tolerance.
