Wireless Bacteria Nanosensor Based on Carbon Nanotubes Functionalized with Ag Nanoparticles

Alvarez-Colón N.I., Arroyo A., Avalos J., Caro G., Colón A., Marra A., Morell G., Weiner B., University of Puerto Rico- Río Piedras Campus, US

Hospital and health communities need a more effective electronic bio-interface to better reduce or eliminate bacterial threat. The biosensor industry fabricates solid devices that are not suitable for biological surfaces such as buccal, skin or [...]

A fluorescent nanosensor base on magnetic silica nanoparticles as illicit drug vapor logic gate

Rouhani S., Institute for Color Science and technology, IR

Herein we report a fluorescent nanosensor base on magnetic silica nanoparticle as illicit drug logic gate. A novel naphthlimide derivative was synthesized (F) , characterized and doped into the magnetic silica nanoparticles (Fe3O4@SiO2-F). Herein we [...]

Autonomous Nanosensor System for Monitoring and Quantifying Arsenic in Water

Coy E., González E., Mosquera N., Salinas S., Yamhure G., Yate L., Pontificia Universidad Javeriana, CO

In present work, we have developed a system for detection and quantification of arsenic in water, based on surface plasmon resonance. The sensor uses a gold self-assembled monolayers on Au(111) substrate. Studies that we have [...]

Mobility of paramagnetic nanoparticles in porous media

Abriola LM., Bagaria H., Johnson K., Pennell KD., Wang Y., Zhang X., Tufts University, US

Stable paramagnetic nanoparticles were prepared and their mobility in reservoir matrix was measured as a function of particle mass loading, rate of sulfonate fraction in coating polymer, and the presence of surfactant.

A Novel Compact Lab-on-a-Chip Nanosensor for In-Channel Liquid Viscosity Detection

Xu J., Xue W., Zhao J., Washington State University Vancouver, US

Real-time monitoring of liquid’s viscosity has significant impacts on many areas such as medicine, biology and petrochemistry. However, most existing sensors have complicated fabrication and testing processes and are not truly compatible with fluidic systems [...]

Label-Free Protein Nano-Biosensor Using Top-Down Fabrication

Ah C.S., Ahn C-G, Baek I-B, Jun M.S., Kim A., Lee S.J., Park C.W., Yang J.H., Yu H.Y., Electronics and Telecommunications Research Institute (ETRI), KR

A nanosensor of n-type Si field-effect transistor (FET) via “top-down method” was employed to monitor PSA with great selectivity and high sensitivity up to 10 pg/mL. When a biomaterial, negatively charged PSA, is introduced through [...]

Nano-Electronic Sensors – Practical Device Designs for Sensors

Bradley K., Cumings J., Gabriel J-C, Gruner G., Star A., Stetter J.R., Nanomix, US

There is often a large gap between laboratory science and practical products. It will take some years to fathom the overall technical importance of nano-technology and even longer to realize societal benefits through practical products. [...]
