Abstract

This study investigates the eco-friendly synthesis and characterization of zinc nanoparticles (ZnNPs) using Stachytarpheta indica aqueous leaf extract. UV–Vis spectrophotometry revealed a prominent absorption peak at 380 nm, confirming nanoparticle formation within the characteristic surface plasmon resonance (SPR) range. Fourier-transform infrared (FTIR) analysis identified functional groups such as hydroxyl, amine, carbonyl, and polysaccharide moieties, suggesting the involvement of phenolics, flavonoids, and proteins in nanoparticle reduction and stabilization. The Scanning Electron Microscopy (SEM) revealed polydisperse, irregularly shaped ZnNPs with porous surface morphology, indicating micro-to-nanoscale size distribution and potential for functional activity. The synthesized ZnNPs demonstrated structural and chemical features consistent with previous plant-mediated nanoparticle syntheses. These findings highlight the efficacy of S. indica extract in producing stable ZnNPs with promising applications in antimicrobial and environmental technologies.
