Electrical Nerve Agents Sensors Based on Chemically Functionalized Nanomaterials

The threat of a chemical attack continues to grow and recent examples such as the terrorist attack of the Metro of Tokyo have shown that organophosphorus agents (OPs) are powerful neurotoxic weapons. There is still [...]

Charge Confinement in Silicon Nanowires by Surface Functionalization

Shih Y.-C., Lee J-H., Lin C-T, Chen C-S, Wu K.-C., National Center for High-performance Computing, TW

Silicon nanowires (SiNWs) are expected to play an important role in nanotechnology because they possess remarkable physical property and compatibility with current Si-based fabrication. They have been successfully used in advance applications such as biosensors, [...]

Increased Piezoresistive Effect in Crystalline and Polycrystalline Si Nanowires

Reck K., Richter J., Hansen O., Thomsen E.V., Technical University of Denmark, DK

This paper presents measurements of the size and doping dependence of the piezoresistive effect in top-down fabricated p-type crystalline and polycrystalline silicon nanowires. Test chips with 6 differently sized piezoresistors and integrated contacts for electrical [...]

Effects of Silicon Nanowires on HepG2 Cell Adhesion and Spreading

Qi S., Yi C., Chen W., Fong C-C, Lee S-T, Yang M., City University of Hong Kong, CN

The unique capabilities of nanomaterials make them good candidates for catalysts, biosensors, and even drug carriers. However, interactions of nanomaterials with biological systems and the environment may lead to potential toxicity. While there have been [...]

Self-Healing Wire-Streaming Processors on 2-D Semiconductor Nanowire Fabrics

Wang T., Bennaser M., Guo Y., Moritz C.A., University of Massachusetts Amherst, US

One of the most promising underlying nanodevice technologies today for nanoscale integrated circuits are semiconductor nanowires (NWs) and arrays of crossed NWs. Researchers have already built FETs and diodes out of NWs. There has also [...]
