摘要

A simple surfactant assisted aqueous solution approach, based on the conventional Tollen's reaction has been applied for the facile syntheses of silver nano-assembly. Nano particle morphologies strongly depend on the temperature adopted during the synthesis. Two-dimensional (2D) nano-disks and three-dimensional (3D) nano-globules with "Cauliflower" like morphology were observed. The unique and distinctive feature of the synthesized silver nano particle in solution is its very high anti-microbial activity. This is evident in very low (4 mu g/ml) inhibitory concentration (MIC) value for Escherichia coli, Vibrio cholerae, Shigella flexneri, Salmonella typhimurium and three varieties of Staphylococcus aureus. This low MIC value is comparable to that of Penicillin and in the cases of E coli and S. aurens (ML 422), the MIC value is as low as 2 mu g/ml which beats even Penicillin. (c) 2007 Elsevier Ltd.
