摘要

The paper reported one-step in situ, facile and green synthesis of silver nanoparticles. In this technique, we had used the sun light as reducing agent as well as new prepared surfactant as catalyst and capping agent for reduction process and for sizing and shaping agent. The silver nanoparticles formation was investigated using UV-vis spectrophotometer, transmission electron microscope (TEM), dynamic light scattering (DLS), Energy Dispersive X-ray (EDX) and FTIR. The results showed formation uniform, well arrangement and hexagonal shape of silver nanoparticle. Both prepared surfactants and surfactants capping silver nanoparticles showed high antimicrobial activity against Gram-positive and Gram-negative bacteria and also against sulfate reducing bacteria (SRB).
