Observational analysis revealed the properties of silver and gold nanoparticles synthesized from stevia extracts, indicating potential eco-friendly applications.
Key Points
Silver nanoparticles showed surface plasmon resonance at 400–450 nm, confirming their synthesis and stability.
Zeta potential analysis revealed polydispersity index values for silver (0.269–0.328) and gold nanoparticles (0.366–0.428).
Characterization methods like UV–Vis spectroscopy and FTIR confirmed effective stabilization of nanoparticles using stevia extracts.
This eco-friendly approach may enable safer, sustainable alternatives for nanoparticle synthesis in biomedicine and antimicrobial applications.
