AI Technical Summary

Technical Problem

Currently, when probiotics are used to treat inflammation-related diseases, nano-selenium has poor adhesion in the intestines and is easily metabolized and excreted, resulting in limited therapeutic effects. Furthermore, it cannot effectively eliminate reactive oxygen free radicals, which can worsen the inflammatory response.

Method used

By growing selenium dots in situ on the surface of probiotics, chimeric selenium dot probiotics are prepared. Using probiotics as the main structure, selenium precursors are adsorbed and reduced by a reducing agent to form selenium dots grown on the surface, thereby enhancing antioxidant activity and intestinal adhesion ability.

Benefits of technology

It enhances the antioxidant activity and intestinal adhesion ability of probiotics, achieving better therapeutic effects on inflammation-related diseases and strengthening the homeostasis and immune regulation functions of the gut microbiota.
