| Summary: | In this study, silver nanoparticles were synthesized and characterized for their physical and antibacterial properties using the explosive wire method. Silver wire with a diameter of 0.3 mm was detonated in an ion-depleted liquid, resulting in the formation of distinctive physical, chemical, and biological properties in the silver nanoparticles. The explosive wire method was employed to prepare silver nanoparticles, which were applied in the field of bacterial inhibition. The optical properties were investigated, revealing strong absorption peaks in the visible and UV regions. These peaks exhibited significant absorption at 240 nm, with the absorption peak positions depending on the size and shape of the particles. Fourier-transform infrared spectroscopy (FTIR) of the silver nanoparticles showed the presence of polar groups such as -COO- and OH-. The absorption spectrum was broad and intense at 3448 cm-1. The effect of the nanoparticles against bacteria was studied. The results demonstrated a pronounced inhibitory effect on bacteria due to the nanoparticles' ability to easily adhere to the bacterial cell membrane and access the bacterial cell's nuclear content. Consequently, a very high inhibition rate was confirmed. |
