Synthesis of copper-tin metal oxide nanoparticles by the electrical explosion wire method and investigation antibacterial properties

Due to the unique physicochemical properties of nanoparticles with the ability to inhibit the growth of bacteria, research has increased on nanoparticles and their applications as the antimicrobial agents. In this study, nanoparticles of copper - tin oxide were synthesized via electrical explosion in water between copper-tin electrodes. This method provides the possibility of producing oxide and metal nanoparticles with high production rates and high surface activity. Copper oxide and tin oxide nanoparticles are known as practical nanoparticles with antibacterial activity. Nanoparticles characterization was performed using the X-ray diffraction, scanning electron microscopy, UV-visible absorption recording and BET analysis. The results showed that by changing the intensity of the applied current, oxide copper - tin with an average size of about 19 to 37.5 nm were formed by electrical explosion of wire. Antibacterial activity of nanoparticles against the E. coli bacteria was evaluated by determining the optical density of various samples with different concentrations of tin and copper oxide nanoparticles. The results showed that the copper - tin oxide nanoparticles possess antibacterial properties and this activity enhances by increasing the concentration of nanoparticles in the liquid medium and reduction the average grain size.
