Probing Protein-Carbohydrate Interactions using Carbon Nanotube Nanodevices for Rapid Bacterial Detection

Vedala H., Chen Y., Star A., University of Pittsburgh, US

In this work, we demonstrate novel nanoelectronics devices based on single-walled carbon nanotube field-effect transistor (NTFET) to probe the interactions between carbohydrates and their recognition proteins called lectins. These interactions are involved in a wide [...]

Development of a capillary-driven, microfluidic, nucleic acid biosensor

He F., Jin S., Dai M., Nugen S.R., University of Massachusetts, US

An ideal point-of-care device would incorporate the simplicity and reliability of a lateral flow assay with a microfluidic device. Our system consists of self-priming microfluidics with sealed conjugate pads of reagent delivery and an absorbent [...]

Starodub N.F., Pilipenko I.V., Pilipenko L.N., Pilipenko I.V., Pilipenko L.N., Katsev A.M., National University of Life and Environmental Sciences of Ukraine, UA

In this report the experimental data about the determination of P toxicity by optical biosensors based on the application of chemiluminescence (ChL) of Daphnia magna living media (ChL-test) and bioluminescence (BL) of Ukrainian strains of [...]

Development and practical application of biosensors based on the nanostructured silicon

Starodub N., Mel’nichenko N., Shmireva A., Shuljak L.N., National University of Life and Environmental Sciences of Ukraine, UA

In this report the principle new instrumental method of the biochemical diagnostics of the bovine leucosis, autoimmune process at the diabetes and the control mycotoxins through the registration of the formation of the specific immune [...]

Force Discrimination for Enhanced Biosensor Specificity of Micro-Retroreflector Assays

Knoop J.D., Kemper S.M., Sherlock T., Cacao E., Ruchhoeft P., Willson R.C., University of Houston, US

In nearly all diagnostic/bioanalytical methods other than mass spectrometry, what is actually detected is a label of some sort, and the sensitivity and simplicity of detection of this label limits assay performance. Non-specific interactions between [...]

Bioreactor with Integrated Nanosensor for the Recording of Extracellular Potential of Nerve Cells: Response oo Inhibitors Record with Algan/Gan Field – Effect Transistor

Cimalla I., Cimalla V., Gebinoga M., Klett M., Lübbers B., Lebedev V., Tonisch K., Cimalla I., Cimalla V., Ambacher O., Schober A., Institute of Micro- and Nanotechnology, TU Ilmenau, DE

Recently sensors based on the group III nitrides attract growing interest in the scientific comunity. It has been shown that sensors made of this material are suitable for recording action potential of muscle cells or [...]

Single-Walled Carbon Nanotube Network based Biosensors using Aptamers and its Characteristics

Kim D.W., Seo S.M., Park Y.J., Seoul National University, KR

We have successfully demonstrated the single-walled carbon nanotube (SWNT) network based biosensor using aptamers as the protein recognition site. The single-walled carbon nanotube network was used to improve the uniformity in I-V characteristics. Aluminum was [...]

The Si-tag for Immobilizing Proteins on a Silicon Device

Kuroda A., Hiroshima University, JP

Targeting functional proteins to specific sites on a silicon device is essential for the development of new biosensors and supramolecular assemblies. Recently, we found ribosomal protein L2 as a silicon-binding protein, which can be used [...]

Modeling the electrical characteristics of FET-type sensors for biomedical applications

Deen M.J., Shinwari M.W., McMaster University, CA

Uniquely examining and identifying biological pathogens is of great importance in health care, as it facilitates early detection, isolation and possibly prevention of many diseases. Availability of highly efficient and easily produced sensors could have [...]

Selective Heating Characterization of Nanoplate Devices for Simultaneous Sensing of Multiple Biomolecule Species at Ultra-low Concentrations

Elibol O.H., Reddy_Jr. B., Bashir R., Purdue University, US

We propose a novel scheme for the en masse fabrication and selective functionalization of field effect silicon nanoplate devices to enable the ultrasensitive, simultaneous and label-free detection of multiple biomolecular species in real time. The [...]
