| Introduction: This study focuses on synthesizing (Zno-NPs) using a green synthesis method with Citrus Maxima extract and investigating their antibacterial and anti-biofilm properties. Nanoparticle, including Zno-NPs, possess unique characteristics such as shape and size dependency, and Citrus fruits, being globally popular, contain various phytochemicals. Methods: The study synthesied of (ZnO-NPs) using pomelo extract and evaluated their antibacterial and anti-biofilm properties. The chemical components were analyzed using GC-Mass, while techniques like UV-Vis spectroscopy, FTIR, SEM-EDX, and XRD were used to characterize the size and morphology of the nanoparticles. Antibacterial activity was tested against E. coli, K. pneumoniae, Pseud.aeruginosa, and Staph. aureus using agar well diffusion method. Additionally, anti-biofilm activity was assessed against biofilm-forming clinical isolates. Results: The study characterized Citrus maxima extract using FT-IR and GC-Mass, confirming its high phytochemical content. The synthesis of (ZnO-NPs) involves reducing Zn+2 to Zn0, confirmed by a color change to a brownish .UV-Vis spectroscopy confirms ZnoNP formation with SPR at 372 nm, and FESEM, EDX, and XRD shows that the nanoparticles have a spherical and crystalline morphology with a size 30-90 nm and an average size 57 nm. The study revealed substantial antibacterial activity in both extract and ZnoNPs,with MIC experiments showing effective antibacterial activity at low doses. Furthermore, the anti-biofilm study demonstrated ZnoNPs' abbility to suppress biofilm development across several bacterial strains. Discussion: This study demostrates how ZnO-NPs made with green chemistry to battle bacterial infections and biofilm-associated disorders, advancing both and environmental health and nanomedicine. | ||
