Mechanisms of action of antimicrobial agents against bacteria.

Dr. Akhavan Clara

Acetonitrile is used as a solvent in the deposition-precipitation process for the synthesis of ZnO-SiO2 nanocomposite. Different analytical methods such as Fournier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and dynamic light scattering (DLS) were used to characterize the synthesized nanocomposite. Using disk diffusion technique and agar well diffusion assay, respectively, the biological potential including antibacterial and antifungal activities is also examined. By using TEM calculations, the particle size of the ZnO-SiO2 nanocomposite was found to be 6.2 nm. The antifungal activity of the nanocomposite was lower than that of bacteria.
