Enhancement of the magneto-optical activity via surface plasmon resonance on Au-Co nanocomposite thin films

Yang K., Clavero C., Skuza J., Lukaszew R.A., College of William and Mary, US

We find that the Au-Co nanocomposite thin films grown at 300 ºC, which exhibit segregate nano-cluster microstructure and smooth surface capable of SPP propagation, exhibit largest magneto-optical effects than the films grown at lower and [...]

A comparative study on sensitivity for biomolecular detection between gold nanoparticles coated and uncoated gold thin film using spectroscopic ellipsometry

Moirangthem R.S., Chang Y-C, Hsu S.-H., Wei P.-K., Research Center for Applied Sciences, TW

We investigate the plasmonic responses of gold nanoparticles (AuNP) coated and uncoated on 30nm gold thin film with aqueous medium having different refractive index using SPR ellipsometry. (See Figure 1) The sensitivities in both cases [...]

New Localized Surface Plasmon Resonance Sensor Utilizing Nanoimprinting Technology

Matsushita T., Nishikawa T., Yamashita H., Nakamura M., Hasui R., Aoyama S., OMRON Corporation, JP

A new localized surface plasmon resonance sensor fabricated by the nanoimprinting technique is presented. Nanoimprinting, one of the most important nanofabrication technologies, can produce stable nanopatterns on a substrate with high throughput. In this study, [...]

Signal Amplification of Surface Plasmon Resonance based on Gold Nanoparticle-Antibody Conjugate and its Application to Protein Array

Lee D-B, Lee W., Lee D-B, Lee W., Kim Y-W., Choi J.W., Sogang University, KR

Nanoparticles have offered many diverse capabilities in bioanalysis and biotechnological applications, due to the intrinsic properties of nanoparticle that is distinguished from bulk materials. The integration of nanoparticle, which exhibit unique electronic, photonic, and catalytic [...]

pH Dependent Optical Properties of Surface Modified Gold Nanoparticles Using a Bovine Serum Albumin Coating

Xu Y., Linares K.A., Meehan K., Love B.J., Love N.G., Love B.J., Love N.G., Virginia Polytechnic Institute and State University, US

Use of gold nanoparticles has significant potential in biosensors. Gold’s surface plasmon resonance (SPR) is influenced by the refractive index of the surrounding environment. Changes in the SPR signal can be correlated to changes in [...]
