Design and Preparation of Silver–Copper Nanoalloys for Antibacterial Applications

摘要: The search for new more effective nanoparticles based antimicrobial agents has been under way in recent decades. Silver are hydrophobic and have a negative charge. We report on the preparation of Ag–Cu bimetallic with various silver contents synthesized by electric explosion two twisted wires metals argon atmosphere. method allows to obtain given composition, high performance scalability. Nanoparticles were investigated using X-ray diffraction, high-resolution transmission electron microscopy, energy dispersive analysis microelectrophoresis techniques. evaluated antibacterial activity against Gram-negative E. coli Gram-positive methicillin resistance S. aureus MRSA. Our study showed that positive zeta potential about 30 mV at pH 7.2 tested bacteria strains, which is close size 20 nm. due prolonged slow release copper ions, makes nanoalloys than Cu Ag metallic nanoparticles. demonstrate their use as promising generation resistant microorganisms.
