Summary:Selenium is an essential nutrient when consumed within safe limits. The toxicity risks are associated with inorganic forms of selenium such as selenite and selenate. This has led to a shift in its convention usage form from inorganic selenite and selenate to selenium nanoparticles or SeNPs. SeNPs are being extensively explored for their positive impacts in fields including agriculture and human health. The new agronomic era has led to the development of various nano-formulations to enhance plant vigor, yield, product quality, shelf life and nutritional status. SeNPs vitally act as immune-booster, antioxidant, antimicrobial, metabolome controllers, bio-assimilators and bio-stimulants for plant health. The recent studies establish the role of SeNPs in the eradication of pre-harvest challenges like high temperature and salinity stress, heavy metal toxicity, pest and microbial attack and metabolic dysfunction. SeNPs also have the ability to neutralize reactive oxygen species (ROS), making them indispensable part of post-harvest management technologies. The functionalization and fabrication of SeNPs into packaging films has been exclusively studied to enhance shelf life, preserve nutritional composition and freshness of processed food products. The review focuses on recent methodologies for SeNP synthesis and their applications in agricultural practices along with detailed explanations of application methods, uptake and transport mechanisms within the plant system, dosage toxicity and crop health management.
