Continuous angular control over anisotropic photoemission from isotropic gold nanoshells

Gold Nanoshells in Biomedical Applications

Magnetically mediated vortexlike assembly of gold nanoshells.

Gold nanoshells currently attract increasing research interests due to the important role in many subjects. For practical applications, random arrangement of the nanoparticles is often unfavored so that the assembly of gold nanoshells is becoming a central issue. We here proposed to utilize time-variant magnetic field to direct the assembly of gold nanoshells. It was discovered that the alterna...

Angular resolved U.V. photoemission from (100) nickel surface

2014 Initial results obtained on a (100) paramagnetic nickel surface by angular-resolved U.V. photoemission are presented. The spectra measured for different electron emission angles are discussed in terms of the calculated band structures and are compared with similar results previously obtained on polycrystalline samples.

A whole blood immunoassay using gold nanoshells.

A rapid immunoassay capable of detecting analyte within complex biological media without any sample preparation is described. This was accomplished using gold nanoshells, layered dielectric-metal nanoparticles whose optical resonance is a function of the relative size of its constituent layers. Aggregation of antibody/nanoshell conjugates with extinction spectra in the near-infrared was monitor...

Isotropic nonmagnetic flat cloaks degenerated from homogeneous anisotropic trapeziform cloaks.

We propose a novel kind of trapeziform cloak requiring only homogeneous anisotropic materials. Large-scale flat cloaks can be degenerated from the general trapeziform cloak with PEC inner boundary, and be realized by isotropic nonmagnetic materials for optical frequencies with controlled index profiles and improved invisibility. With the support of PEC inner boundary, large vehicles and objects...
