Surface plasmon resonance and magnetism of thiol-capped gold nanoparticles.
Surface plasmon resonance measurements and magnetic characterization studies have been carried out for two types of thiol-capped gold nanoparticles (NPs) with similar diameters between 2.0 and 2.5 nm and different organic molecules linked to the sulfur atom: dodecanethiol and tiopronin. In addition, Au NPs capped with tetraoctyl ammonium bromide have also been included in the investigation sinc...

متن کاملSelective assembly of nanoparticles on block copolymer by surface modification
We have developed a method to selectively deposit nanoparticles on the ordered nanoscale elements of PS–PI–PS (polystyrene–polyisoprene–polystyrene) block copolymer film. The process utilizes reactive ion plasma to selectively modify the PS surface with amine groups to electrostatically attract negatively charged Au nanoparticles. In spite of the strong interparticle Coulombic repulsion, the de...
متن کاملFast, single-step, and surfactant-free oligonucleotide modification of gold nanoparticles using DNA with a positively charged tail.
Fast modification of large gold nanoparticles with DNA is achieved by using DNA with a polycationic tail. The conjugated DNA is available for specific hybridization, and therefore can be used for DNA-based assays or for constructing nanoparticle superstructures based on DNA hybridization.
متن کاملEngineering 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...
