Biosynthesis of Strontium Nanoparticles Using Mimosa pudica and its Antioxidant Effect

A BSTRACT A new area of nanotechnology, “green synthesis” studies nanomaterials utilizing natural biomaterials like plants, flowers, and microbesGreen nanoparticle synthesis offers various benefits, such as cost efficiency, pollution reduction, and environmental compatibility. Among nanoparticles, metallic variants have garnered the greatest attention due to their unique physical and chemical attributes. Strontium (Sr), known for promoting growth, aiding bone regeneration, and stimulating calcium signaling, holds significance in the medical domain. Consequently, Sr-based nanoparticles have gained interest in medical and dental applications due to their resemblance to calcium properties. Researchers worldwide are drawn to Mimosa pudica because of its pharmacological properties, including its ability to treat wounds, and its anti-diabetic, anti-toxin, anti-hepatotoxin, and antioxidant effects. Mimosa pudica mediated strontium nanoparticles’ antioxidant activity was tested against FRAP assay, H2O2 assay, and DPPH assay with ascorbic acid as standard, where in all three assays, increasing concentration of Mimosa pudica mediated strontium nanoparticles exhibited increasing antioxidant activity which was similar to the ascorbic acid. Hence, this can be used as a novel antioxidant agent in the near future.
