Synergistic Interaction between Anionic and Nonionic Surfactant: Application of the Mixed Micelles Templates for the Synthesis of Silver Nanoparticles

Interaction between the anionic and nonionic surfactant at bulk and air/water interface has been studied. The synergistic interaction between surfactants was found in both in bulk solution as well as the interface. The different physicochemical parameters of the free surfactant monomers up to the point of their critical micelle concentration (cmc) have been evaluated and discussed in detail. The synergistic interactions have been analyzed using various theoretical models reported i.e., Clint, Rubingh, Maeda and Rosen models. The spectrophotometric and structural analyses have been achieved for the formation of silver nanoparticles using sodium borohydride as reducing agents and pure as well as mixed surfactant systems as capping agents. Antimicrobial activities of the synthesized nanoparticles were performed against both Gram-negative (P. aeruginosa and Klebsiella Pneumonia) and Gram- positive (Micrococcus luteus) bacteria.
