Green biosynthesis of silver - functionalized multiwalled carbon nanotube (Ag/FMWCNT) nanohybride from silver nitrate solution using water extract of Satureja hortensis L as reducing agent and FMWCNT as anchoring agentat room condition was successfully carried out. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized Ag particles The synthesized nanocomposite were characterized using ultraviolet-visible spectroscopy (UV-Vis), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and powder X-ray diffraction (XRD). The UV-Vis spectra of the Ag/FMWCNT nanocomposite showed absorption peak at around 401nm. SEM and TEM studies showed that the average particles size of Ag/FMWCNT nanocomposite was about 16.05 nm and also XRD patterns indicated that the structure of the nanocomposite is face-centered cubic.The antibacterial effects of Ag/FMWCNT on Gram positive and Gram negative bacteria were also performed.
