Abstract EN
Sol-gel method was use to prepare Ag-SiO2 nanoparticles.
Crystal structure of the nanocomposite was investigated by means of X-ray diffraction patterns while the color intensity was evaluated by spectrophotometry.
The morphology analysis using atomic force microscopy showed that the average grain sizes were in range (68.96-75.81 nm) for all samples.
The characterization of Ag-SiO2 nanoparticles were investigated by using Scanning Electron Microscopy (SEM).
Ag-SiO2 NPs are highly stable and have significant effect on both Gram positive and negative bacteria.
Antibacterial properties of the nanocomposite were tested with the use of Staphylococcus aureus (S.
aureus) and Escherichia coli (E.
coli) bacteria.
The results have shown antibacterial effect of the Ag-SiO2 prepared as nanogel and nanopowder states, while the Ag-SiO2 nanopowder showed the highest capability against S.
aureus.
Both methods of biofilm showed an inhibition effect for Ag-SiO2 NPs, the synthetic Ag-SiO2 NPs showed highest inhibition effect on Gram positive bacteria S.
aureus by using the biofilm microtiter method
