Silver nanoparticles were prepared in situ using sunlight and cationic surfactants. Silver nano-particles were confirmed using UV–vis spectrophotometry, transmission electron microscopy(TEM), electron diffraction, dynamic light scattering(DLS) and FTIR. Increasing the hydrophobic chain length of surfactants increase the amount of silver nano-particles formed in addition to increasing their stability.The results showed formed, uniform, well arranged hexagonal and spherical shapes. The prepared silver nanoparticles exhibit enhanced biological activity against Gram-positive, Gram-negative bacteria and sulfate reducing bacteria(SRB).
