Giant magnetic susceptibility of gold nanorods detected by magnetic alignment.

We have determined the magnetic properties of single-crystalline Au nanorods in solution using an optically detected magnetic alignment technique. The rods exhibit a large anisotropy in the magnetic volume susceptibility (Δχ(V)). Δχ(V) increases with decreasing rod size and increasing aspect ratio and corresponds to an average volume susceptibility (χ(V)), which is drastically enhanced relative...

Resorcinarene-Encapsulated Gold Nanorods: Solvatochromatism and Magnetic Nanoshell Formation.

Gold nanorods (GNRs) were encapsulated and dispersed into organic solvents by tetrabenzylthiol resorcinarene (TBTR) and by a poly(dithiocarbamate) derived from tetra- N-methyl(aminomethyl)resorcinarene (TMAR-DTC), formed by the in situ condensation of TMAR with carbon disulfide. The latter proved to be highly effective at enabling the redispersion of GNRs in various organic solvents. GNRs encap...

Investigation and Determination of Osvix by Gold Nanorods by Spectrophotometry

Background and Aims: Osvix drug is an internal brand of Plavix, which is used to prevent blood coagulation in many heart diseases. The aim of the present study was to measure this drug by gold nanorods in optimum conditions and in real samples. Material and Methods: Gold nanorods were synthesized by the seeded-mediated method. Measurement of Osvix drug by gold nanorods was performed by optimizi...

Giant-magnetic clusters and susceptibility enhancement in Pd-Ni alloys.

A recently developed formalism is used to calculate the saturation magnetization and temperaturedependent, exchange-enhanced Pauli susceptibility of paramagnetic and weakly ferromagnetic Pd-Ni alloys. The eff'ects of quantum and thermal spin fluctuations are included in alloy calculations for the first time, through the use of a semiphenomenological theory consistent with the results of renorma...

Magnetic Nanorods for Optofluidic Applications

We have developed a method for laser beam manipulation by using a colloid of nickel nanorods produced by electroplating chemistry. It is shown that the shape of the laser beam passing through a colloid of nickel nanorods can be altered by varying the applied magnetic field. This effect is caused by multiple scattering and diffraction of the laser beam by the nanorods. Compared with spherical na...
