Applicable orientation of eco-friendly phyto-synthesized selenium nanoparticles: Bioactive investigation and dye photodegradation

The simple and eco-friendly approach to the selenium nanoparticles (SeNPs) synthesis process was carried out in this study by using Pseuderanthemum palatiferum leaves (P.palatiferum) extract, which possesses a large number of flavonoids, triterpenoids, and polyphenols, as both a reducing and stabilizing agent. Along with those, the characterization of SeNPs was analyzed through modern analytical methods, confirming the spherical shape with an average diameter of 247 nm and uniform distribution. The fundamental antibacterial performance toward strains of Pseudomonas aeruginosa (P. aeruginosa), Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli) was recorded as inhibition diameters of 14.67, 13.67, and 14.67 mm, respectively. Furthermore, the anticancer ability concerning liver cancer cells (Hep-G2), lung cancer cells (A549), and human embryonic kidney cells (HEK-293) of SeNPs was also given excellent with the inhibition ability up to 100% at a concentration of 256 mu g/mL. Besides, SeNPs showed the photodegradation efficiency of organic dyes including methylene blue and crystal violet both up to 99%. Conclusively, the as-synthesized SeNPs, with the synergistic assistance of the P. palatiferum leaves extract, perform as a potential candidate in medicine and environmental remediation.
