AI Technical Summary
Existing technologies struggle to produce low-cost, environmentally friendly, uniformly sized, and well-dispersed nano-selenium materials. Furthermore, the large demand for organic reagents and stringent preparation conditions make them unsuitable for large-scale industrial production.
Bio-derived selenium nanomaterials were prepared by mixing bio-derived walnut septum extract with sodium selenite and quercetin, followed by constant-temperature stirring, filtration, dialysis, and drying steps, avoiding high temperature and high pressure, and using simple equipment.
The prepared bio-derived selenium nanomaterials have uniform particle size and good dispersibility, and possess excellent free radical scavenging ability and antibacterial activity. They are suitable for selenium supplement preparations, reducing the need for toxic and harmful reagents, and are suitable for large-scale industrial production.
