  In this work, facile, rapid and green biosynthesis and characterization of
silvermontmorillonite nanocomposite is reported at room temperature. Silver
nanoparticles were prepared by water extract of Satureja hortensis as the
reducing agent and MMT as interlamellar space for controlling the size of
Ag-NPs. MMT was suspended in the aqueous AgNO3 solution, and after the
absorption of silver ions, Ag+ was reduced to Ag0 using water extract of
Satureja hortensis. Evaluations of the antibacterial properties are also
reported. The nanocomposite was characterized by ultraviolet-visible
spectroscopy, powder Xray diffraction, scanning electron microscopy and
transmission electron microscopy . TEM study showed the formations of
nanocomposite using water extract of Satureja hortensis L in the 4.88-26.70 nm
range and an average particles size of 15.79 nm. In addition, XRD study showed
that the particles have a face centered cubic structure. The nanocomposite
showed antibacterial properties against Gram positive and negative bacteria.
