Protective Sensor Coatings for High-Throughput Screening of Hydrogen-Producing Microbes

Pryce Lewis H., GVD Corporation, US

Microbe-based hydrogen production is a potentially cost-effective, non-polluting approach to the production of hydrogen. Research efforts are underway to identify, isolate, and enhance microbial strains which facilitate direct sunlight-to-hydrogen conversion. These efforts are hampered by [...]

‘Lab on a chip’ Label Free Protein Sensor Systems Based on Polystyrene Bead and Nanofibrous Solid Supports

Kunduru V., Prasad S., Patra P.K., Sengupta S., Portland State University, US

Polystyrene bead and electrospun polystyrene nanofibers are employed as subjects of study in this protein biomarker sensor. The study is conducted to compare the sensitivity and efficiency of the polystyrene nanofibers and microspheres as protein [...]

Feasibility Study of Cochlear-like Acoustic Sensor using PMN-PT Single Crystal Cantilever Array

Hur S., Lee S.Q., Kim W.D., Korea Institute of Machnery & Materials, KR

The mammalian cochlea is an organ that performs the conversion of the incoming mechanical energy into electrical signals in the auditory nerve fibers. Current cochlear Implants have been developed in an effort to restore sensorineural [...]

Sensing Weak Magnetic Field By Leaving Biosystems and A Magnetoreseption Mechanism For Navigation

Lyshevski S.E., Rochester Institute of Technology, US

This paper examines and demonstrates a possible mechanism of sensing weak magnetic fields in biosystems.

Pressure sensor data processing for vertical velocity measurement

Husak M., Jakovenko J., Stanislav L., Czech Technical University in Prague, CZ

There are design and realization of a sensor system for vertical velocity measurement using pressure sensor in the paper. Problem of nonlinearity due to the exponential function of air pressure versus altitude is discussed in [...]

FIB generated antimony nanowires as chemical sensors

Lugstein A., Schöndorfer C., Bertagnolli E., Technical University Vienna, AT

Sb nanowires with a homogeneous distribution of diameters of about 25 nm and length up to several microns are synthesized in a self-assembling process without any additional material source at room temperature by the impact [...]

Micrwave based microfluidic sensor

Tanbakuchi H., Bynum M., Brennen R., Whitener M., Agilent Technologies, US

SPR ( surface Plasmon Resonance) is an non destructive sensor capable of measuring the changes in refractive index above the gold surface (~300 nm) .The advantage of the SPR is in its capability of looking [...]

Agent Reactive Modulated Optical Reflector for Hazardous Agent Detection

Kovalev A.E., Bray M.G., Mayer T.S., Werner D.H., Pennsylvania State University, US

We demonstrate a standoff passive sensor working in the near infrared range. The device uses a platform based on dielectric and metallo-dielectric layers. The sensor demonstrated a significant change in the reflection coefficient if exposed [...]

Structure-property relationships in Pd/Polycarbonate based chemical sensors

Atre S.V., Valmikanathan O.P., Meka D.B., Prasad S., Oregon Nanoscience & Microtechnologies Institute, US

The effects of nanparticle surface chemistry, size, concentration and distribution on the properties of Pd/polycarbonate nanocomposites was investigated. Interesting trends in electrical conductivity and thermal stability of the nanomposites were identified. These trends were used [...]

Au Nanoparticle Coupled- Surface Plasmon Resonance Immuno-sensor for Sensitivity Enhancement

Kim H-S, Kim J.H., Kim H-S, Kim J.H., Ko S-H., Cho Y-J, Kim H-S, Kim J.H., Ajou University, KR

In order to overcome the sensitivity limitation of SPR, nanoparticle-coupled SPR biosensors have explored since nanoparticles may significantly enhance the sensitivity by 1-2 orders of magnitude. Although the nanoparticle conjugated method contributes to the enhancement [...]
