A combined nanoplasmonic and electrodeless quartz crystal microbalance setup

07 Dec 2009

We have developed an instrument combining localized surface plasmon resonance (LSPR) sensing with electrodeless quartz crystal microbalance with dissipation monitoring (QCM-D). The two techniques can be run simultaneously, on the… Read more

Nanoplasmonic Probes of Catalytic Reactions

22 Oct 2009

Optical probes of heterogeneous catalytic reactions can be valuable tools for optimization and process control because they can operate under realistic conditions, but often probes lack sensitivity. We have developed… Read more

Hole-Mask Colloidal Lithography

29 Nov 2007

Hole-mask colloidal lithography (HCL) represents a truly versatile and simple bottom-up nanofabrication method based on colloidal self-assembly lithographic patterning. The HCL technique provides an effective means of patterning vast surface… Read more

Hydrogen Storage in Pd Nanodisks Characterized with a Novel Nanoplasmonic Sensing Scheme

13 Sep 2007

A novel nanoplasmonic sensing scheme is introduced based on remote real-time detection of induced electronic and shape/structural changes in a metal nanoparticle during the metal−hydride formation process. The localized surface… Read more

Absorption and scattering of light by Pt, Pd, Ag, and Au nanodisks: Absolute cross sections and branching ratios

15 May 2007

Localized surface plasmons (LSPs) of metallic nanoparticles decay either radiatively or via an electron-hole pair cascade. In this work, the authors have experimentally and theoretically explored the branching ratio of… Read more

Sensing Characteristics of NIR Localized Surface Plasmon Resonances in Gold Nanorings for Application as Ultrasensitive Biosensors

13 Apr 2007

The optical responses of 75−150 nm diameter gold nanorings to changes in local refractive index have been quantified by near-infrared extinction spectroscopy and compared to DDA calculations and an analytical… Read more
