| 1 | Preparation of capped silver nanoparticles using sunlight and cationic surfactants and their biological activity显示文摘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). | Samy M.Shaban Ismail Aiad Mohamed M.El-Sukkary E.A.Soliman Moshira Y.El-Awady | 2015 | Chinese Chemical Letters2015，26，11： | 2 |
| 2 | Synthesis of newly cationic surfactant based on dimethylaminopropyl amine and their silver nanoparticles:Characterization;surface activity and biological activity显示文摘The chemical structure of newly synthesized cationic surfactants based on Schiff base was confirmed using Fourier transform infrared spectroscopy,proton nuclear magnetic resonance spectroscopy,and mass spectroscopy.The synthesized surfactants were used in the synthesis of silver nanoparticles by a simple one-step method.The silver nanoparticle(AgNPs) formation was confirmed using transmission electron microscopy(TEM),electron diffraction(SAED),dynamic light scattering(DLS),and energy dispersive X-ray spectroscopy(EDX).The structure of the surfactant played an important role in the synthesis process.Increasing the hydrophobic chain length,the stability,and the amount of surfactant increased the quantity of AgNPs formed.The surface activity of the synthesized cationic surfactants was determined using surface tension measurements at three different temperatures.The synthesized surfactants showed a high tendency toward adsorption and micellization.Increasing the hydrophobic chain length of the synthesized surfactant increased its adsorption.Screening the synthesized cationic surfactants and their nano-form against bacteria and fungi showed that they are highly effective.The silver nanoparticles enhanced the biological activity of the synthesized cationic surfactants. | Samy M.Shaban Ismail Aiad Mohamed M.El-Sukkary E.A.Soliman Moshira Y.El-Awady | 2017 | Chinese Chemical Letters2017，28，2： | 0 |
