Attenuated-Affinity Biotin Analogs for Catch-and-Release with Streptavidin

Corry S., Ying L-Q, Branchaud B., Life Technologies, US

The binding between streptavin and biotin, which is one of the strongest non-covalent interactions known in nature, is used ubiquitously in molecular biology. However, when a biotinylated molecule is captured for testing purposes and cannot [...]

A Tunable Dispersive Optical System

Shieh K-W, Hsieh J., Chou H-Y, Precsion Instrument Development Center, TW

Pitch-tunable gratings can find many applications and have been widely investigated. However, they are limited to out-of plane type, which increase the cost for alignment and assembly. Instead, an in-plane type can built more micro [...]

RF-MEMS switching LC-tank network for multiband VCO

Gaddi R., Gnudi A., Bellei M., Margesin B., Giacomozzi F., ARCES - University of Bologna, IT

A recently developed RF-MEMS technology based on high resistivity Silicon substrate and suspended gold membrane is proposed for the design of a switching dual frequency LC-tank, for the implementation of a hybrid MEMS-CMOS dual-band voltage [...]

A MEMS Tunable Inductor

Zine-El-Abidine I., Okoniewski M., McRory J.G., University of Calgary and TRLabs, CA

This paper reports a single-wafer micromachined radiofrequency (RF) inductor that can be integrated in a conventional RFIC device. The inductor achieved a quality factor greater than 9 at 5Ghz and a self-resonance frequency well above [...]

RF-MEMS Voltage Tunable Capacitor using Electrostatic Forces

Lee J., Kim Y., Na D., Park S., Kyungpook National University, KR

In this paper, we have proposed a fabrication method of a RF-MEMS voltage tunable capacitor using Au-electroplating technique, which has one movable parallel plate with various structure of beams. We applied an electrostatic method and [...]
