Design and development of anisotropic inorganic/polystyrene nanocomposites by surface modification of zinc oxide nanoparticles.

Anisotropic yolk/shell or Janus inorganic/polystyrene nanocomposites were prepared by combining miniemulsion polymerization and sol-gel reaction. The morphologies of the anisotropic composites were found to be greatly influenced by surface modification of zinc oxide (ZnO) nanoparticle seeds. Two different types of the oleic acid modified ZnO nanoparticles (OA-ZnO) were prepared by post-treatmen...

Bacterial Synthesis of Anisotropic Metal Nanoparticles

This chapter describes the biological synthesis of anisotropic metal nanoparticles using the bacterium Actinobacter spp. The biogenic gold nanoparticles thus synthesized show triangular and hexagonal morphology with edge lengths between 0.05 μm to 2 μm. The surface topography of triangular gold particles indicated that they are ~ 9 nm thick. These flat particles show a strong absorption in the ...

Surface modification of Y2O3 nanoparticles.

Rare earth ion-doped yttrium oxide (Y2O3) nanocrystals are nontoxic and can be prepared as upconversion materials for cellular imaging, but they do not suspend well in water. In contrast to their tendency to dissolve in acidic media, yttria (Y2O3) nanoparticles readily react with phosphonic acids to give phosphonate-bonded yttria particles. Through the choice of phosphonic acid, the hydrophilic...
