Abstract:

The development of the eco friendly procedures makes nanoparticles as the rapidly growing field of nanotechnology. Amongst, the silver nanoparticles have become prominent in the field of medicine to their peculiar antimicrobial properties. In the present study we suggest an eco friendly procedure of extracellular synthesis of silver nanoparticles with an average sizes of 5-50nm using an Actinomycete isolated from mangrove soil.  The silver nanoparticles were characterized with UV-Visible spectrophotometer, FTIR and TEM analysis. The synthesized silver nanoparticles showed an excellent antibacterial property on multidrug resistance gram positive and gram negative bacterial strains.

Synthesis and characterization of silver nanoparticles for antibacterial activity

We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...

Silver colloid nanoparticles: synthesis, characterization, and their antibacterial activity.

A one-step simple synthesis of silver colloid nanoparticles with controllable sizes is presented. In this synthesis, reduction of [Ag(NH(3))(2)](+) complex cation by four saccharides was performed. Four saccharides were used: two monosaccharides (glucose and galactose) and two disaccharides (maltose and lactose). The syntheses performed at various ammonia concentrations (0.005-0.20 mol L(-1)) a...
