Abstract
Two-dimensional staggered silver nanosheets were synthesized using a facile atmospheric microplasma electrochemical process at room temperature. It is an environmental friendly technique that does not include toxic reducing agents. In this technique, microplasma directly reduces Ag+ ions into an electrolyte solution. The synthesized silver nanosheets were investigated by scanning electron microscope, x-ray diffraction, ultraviolet-visible spectroscopy and fourier transform infrared spectroscopy. This type of morphology has not yet been reported using a microplasma technique. The antibacterial activity of the as-synthesized nanosheets against Klebsiella pneumoniae, the Staphylococcus strain, Escherichia coli and Acinetobacter was carried out using a disc diffusion method. The results indicated that these sheets show significant antibacterial activity against Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli and Acinetobacter compared with that of the standard antibiotic.
