Summary
This narrative review synthesises recent advances in selenium nanoparticle (SeNP) technology and their agronomic and nutritional applications. The authors examine how zero-valent elemental SeNPs mitigate toxicity risks of conventional selenite and selenate formulations whilst enhancing bioavailability, plant stress tolerance, and crop nutritional density. The review identifies methodological gaps in SeNP research and proposes a characterisation framework and research priorities for future studies.
Regional applicability
The review is geographically non-specific and presents a global synthesis of nanotechnology applications in agriculture. Its findings are broadly transferable to United Kingdom crop production systems, though uptake would depend on regulatory approval of engineered nanoparticles and validation in temperate climate conditions.
Key measures
Plant growth metrics, photosynthetic pigment content, nutrient uptake, seed quality, yield, nutritional content, stress resilience markers, antimicrobial properties
Outcomes reported
The review examines how engineered selenium nanoparticles (SeNPs) influence plant growth, stress tolerance, nutrient uptake, seed quality, and crop nutritional content compared to conventional selenium formulations. It synthesises evidence on SeNP synthesis methods, agrobiological impacts, and applications in sustainable agriculture and food safety.
