Characterization of An Integrated 3-Axis CMOS-MEMS Accelerometer

Qu H., Fang D., Xie H., Oakland University, US

This paper reports an integrated 3-axis CMOS-MEMS accelerometer with single proof mass. Sensor design, fabrication process are introduced and detailed characterization of this small-sized accelerometer is addressed. Compared to the previously reported 3-axis accelerometers, most [...]

Fabrication of a Real-Time Reactive Ion Etching Resonant Sensor Using a Low Temperature Sacrificial Polymer

Morris B.G., Joseph P.J., May G.S, Georgia Institute of Technology, US

This paper presents a sacrificial layer process using a low temperature polymer as a sacrificial material for fabricating a surface micromachined in-situ reactive ion etching (RIE) resonant sensor. The sensor monitors film thickness and etch [...]

MEMS Sensors for Harsh Environment Applications

Nieva P.M., University of Waterloo, CA

Micro Electro Mechanical Systems (MEMS) for harsh environment applications are becoming increasingly important. They are recognized as essential for reducing weight and volume in strategic market sectors such as automotive, aerospace, turbomachinery, oil well/logging equipment, [...]

Nano-structure or nano-system: opportunities and pitfalls

French P., Delft University of Technology, NL

Scaling down has revealed many new effects leading to new devices able to measure faster and more accurately than traditional devices. They also present challenges in terms of connecting to the macro-world and in reliability. [...]

Qdots as smart pH probes monitor proton flux driven by ATP synthesis and optical coder for detection various virus

Jiachang Y., Institute of Biophysics, Chinese Academy of Sciences, CN

Here we described a novel approach of CdTe quantum dots fluorescence probes to improve the detection of proton flux through F1F0-ATP by ATP synthesis. It was found that both the CdTe quantum dots (535nm, 585nm) [...]

Nitrosyl-iron Complexes as Potent Smart Nitric Oxide Biosenors: MRI imaging Techniques in Progress

Sharma R., Kwon S., Florida State University, US

Nitric oxide is a gaseous, free radical which plays a role as a diffusible intracellular second messenger. It is emerging as biosensor for monitoring myocardial ischemia and the effect of HMG-CoA reductase inhibitor statins. Presently, [...]

Qdots as smart pH probes monitor proton flux driven by ATP synthesis and optical coder for detection various virus

Zhang Y., Deng Z., Yue J., Tang F., Institute of Biophysics, Chinese Academy of Sciences, CN

The chromatophores allow self assemble with the negatively charged Qdots through electrostatic reaction. The fluorescence intensity of Qdots not only was vastly different in the solution and on the surface of chromatophores, but also for [...]

Modified Nanoparticle Films for Transmission Plasmon Biosensing

Bonroy K., Frederix F., Reekmans G., Jans H., Jans K., Jans H., Jans K., Van de Broek B., De Palma R., Borghs G., IMEC, BE

The principle of the Transmission Plasmon Biosensor is based on LSPR of metal nanoparticles attached to a transparent substrate. When the analyte of interest binds to the bioreceptors immobilized onto these nanoparticles, the absorption properties [...]

Quantum Dots as Replacements for Tandem Dyes in Flow Cytometry

Buller G.M., Zhang Y.Z., Godfrey W.L., Invitrogen, US

Qdot® nanocrystals provide fluorescent labels that can be excited with UV or violet light sources, but can also be used with longer wavelength excitation. In flow cytometry, investigators achieve greater multiplexing of cellular markers by [...]
