Synthesis of silver nanoparticles in reverse micelles stabilized by natural biosurfactant

Biosurfactants and Bioemulsifiers Biomedical and Related Applications – Present Status and Future Potentials

“…The synthesized nanoparticles were found to be fully crystalline and spherical in shape with uniform distribution and increasing the pH of the solution decreased the size of the nanoparticles. Xie et al, (2006) were also able to synthesize silver nanoparticles in rhamnolipid reverse micelles while in another study rhamnolipids were used as capping agents for the synthesis of ZnS nanoparticles in aqueous medium ). Sophorolipids were also tested for use in nanoparticles synthesis and reported to be good reducing and capping agents for cobalt and silver particles (Kasture et al, 2007, as cited in Van Bogaert & Soetaert, 2010.…”

Synthesis of silver/montmorillonite nanocomposites using γ-irradiation

“…In particular, its interlayer space has been used for the synthesis of material and biomaterial NPs as the support for anchoring transition metal complex catalysts and as adsorbents for cationic ions. 30,31 In addition, various production methods have been described for the synthesis of Ag-NP colloids using silver salt as the initial materials; for instance, chemical reduction, [32][33][34][35] aerosol spraying technique, 36 reverse micelle, 37 lamellar liquid crystal, 38 microemulsion, 39 micelle, 40 capping agent method, 41 and photochemical reduction (ie, microwave, 42 electron beam, 43 ultraviolet (UV)-irradiation, 44,45 and γ-irradiation). [46][47][48] Of these techniques, the use of γ-irradiation in the preparation of Ag-NPs has been demonstrated to have a number of highly advantageous properties compared with conventional chemical and photochemical methods, namely:…”

Surface Plasmon Resonance study of Ag nanoparticles colloidal

“…Proper to their small size, nanoparticles have a high surface to volume ratio, this increases the surface energy compared with that of bulk materials. The high surface to volume ratio together with the size effect gives nanoparticles discriminative different properties (chemical, optical, electronic and magnetic) from those of bulk material [1][2][3][4][5]. Different preparation methods have been reported for the preparation of metal oxide nanoparticle, notable examples comprise, laser ablation, gamma irradiation , electron irradiation , chemical reduction , photochemical methods, microwave processing, and biological synthetic methods [6].…”
