Two-dimensional staggered silver nanosheets were synthesized using a facile atmospheric micro-plasma 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.
