Synthesis of ZnO Nanoparticles From Pergularia daemia Fibre: Potential for Caries Prevention and Infection Control

Antimicrobial resistance and biofilm-associated infections present major challenges in oral healthcare, necessitating sustainable nanomaterials with multifunctional efficacy. This study reports the green synthesis of zinc oxide nanoparticles (ZnO NPs) from Pergularia daemia ( P. daemia ) fibre (PDF) extracts and evaluates their structural, thermal, and biological properties for dental and biomedical applications. ZnO NPs were synthesised using aqueous PDF extracts as natural reducing and stabilising agents. Structural crystallinity was examined by X-ray diffraction (XRD), functional groups by Fourier-transform infrared spectroscopy (FTIR), morphology by scanning electron microscopy (SEM), and thermal stability…
