Self-assembly of Au Nanoparticle-containing Peptide Nano-rings on Surfaces

Self-assembly of thiolated cyanine aggregates on Au(111) and Au nanoparticle surfaces.

Heptamethinecyanine J-aggregates display sharp, intense fluorescence emission making them attractive candidates for developing a variety of chem-bio-sensing applications. They have been immobilized on planar thiol-covered Au surfaces and thiol-capped Au nanoparticles by weak molecular interactions. In this work the self-assembly of novel thiolated cyanine (CNN) on Au(111) and citrate-capped AuN...

Self-assembly of cobalt nanoparticle rings.

Weakly ferromagnetic cobalt nanoparticles can assemble spontaneously into nanosized "bracelets" when dispersed in organic solvents containing resorcinarenes as surfactants. Bracelet self-assembly occurs in solution and is directed by magnetic dipolar interactions, whereas nanoparticle rings with larger diameters are produced by evaporation-driven flow on wetted surfaces.

Engineering Nano-aggregates: β-Cyclodextrin Facilitates the Thiol-Gold Nanoparticle Self-Assembly

The structure and morphology of nonmaterial formed by colloidal synthesis represent a subject of interest as it is a factor deciding the physicochemical properties and biological applications of nanostructures. Among various nanoparticles, gold can develop fractal assembled patterns. Herein, we report a nano-aggregate of a thiol-on-gold self-assembled structure and the influence of β-cyclodextr...

Self-assembly of highly oriented lamellar nanoparticle-phospholipid nanocomposites on solid surfaces.

When nanoparticles (NPs) are embedded in organic matrices, the materials can show not only combined properties of the original components but also improved performances not seen in the original components.1 To this end, it is important to control the size, shape, and dispersion of the NPs on a chemically diverse range of supports. However, controlling materials at the nanometer scale is of grea...
