Plant-mediated nanoparticle synthesis is a revolutionary technique with numerous applications in agriculture, food processing, and medicine. This present study reports Punica granatum leaf extract is capable of the green and eco-friendly synthesis of silica nanoparticles which provides simple, cost effective, and efficient methodology. Silica nanoparticles were synthesized by a biological method using Tetra Ethyl Ortho Silicate. Biosynthesized silica nanoparticles characterized by X-Ray Diffraction Analysis, Scanning Electron Microscopy, Energy Dispersive X-Ray Spectroscopy, and Fourier Transform Infrared Spectroscopy. All the analysis and characterization were determined that particles were spherical, amorphous nature with an average size of 12 nm. P. granatum assisted silica nanoparticles were tested for antibacterial activity by well diffusion method against two-gram negative bacterial pathogens (E. coli and Salmonella Sp.). The antibacterial studies prove that P. granatum assisted silica nanoparticles to have good antibacterial properties. These studies will help to find a new nano drug or medicine for multidrug-resistant bacteria.

“…The obtained FTIR spectra of the biosynthesized SiO 2 nanoparticles were compared with the previous literature, and there are no additional peaks appearing in the FTIR spectra, which would indicate the presence of any impurities. Plant molecules assist in producing Si 4+ to O 2− ions and stabilizing the ions in the biosynthesis of SiO 2 nanoparticles [54][55][56][57][58].…”

The present work shows the obtainment of biosynthesized SiO2 with the aid of Jasminum grandiflorum plant extract and the study of its photocatalytic ability in dye degradation and antibacterial activity. The obtained biosynthesized SiO2 nanoparticles were characterized using X-ray diffractometer analysis, Fourier transform infrared spectroscopy analysis, ultraviolet–visible diffuse reflectance spectroscopy, field-emission scanning electron microscope with energy-dispersive X-ray analysis, transmission electron microscopy and X-ray photoelectron spectroscopy. The UV-light irradiated photocatalytic activity of the biosynthesized SiO2 nanoparticles was examined using methylene blue dye solution. Its reusability efficiency was determined over 20 cycles and compared with the commercial P-25 titanium dioxide. The bacterial resistivity of the biosynthesized SiO2 nanoparticles was examined using S. aureus and E. coli. The biosynthesized SiO2 nanoparticles showed a high level of crystallinity with no impurities, and they had an optimum crystallite size of 23 nm, a bandgap of 4 eV, no Si-OH groups and quasi-spherical shapes with Si-2p at 104 eV and O-1s at 533 eV. Their photocatalytic activity on methylene blue dye solution could reach 90% degradation after 40 min of UV light exposure, and their reusability efficiency was only 4% less than that of commercial P-25 titanium dioxide. At the concentration of 100 μg/mL, the biosynthesized SiO2 nanoparticles could allow the resistivity of E. coli to become borderline to the resistant range of an antibiotic called Amikacin.
