New Chemically Functionalized Nanomaterials for Electrical Nerve Agents Sensors

A chemical receptor specific to traces of organophosphorus nerve agents (OPs) has been synthesized and grafted to carbon nanotubes and silicon nanowires in order to make electrical sensors. Our results show that it is possible to detect efficiently sub-ppm traces of OPs with excellent selectivity notably with the use of silicon nanowires by monitoring the Drain-Source current of the SiNW-FET at...

Sub-ppm detection of nerve agents using chemically functionalized silicon nanoribbon field-effect transistors.

Chemically functionalized carbon nanotubes.

Since their discovery, carbon nanotubes have attracted the attention of many a scientist around the world. This extraordinary interest stems from their outstanding structural, mechanical, and electronic properties. In fact, apart from being the best and most easily available one-dimensional (1D) model system, carbon nanotubes show strong application potential in electronics, scanning probe micr...

Nanomaterials in Sensors

This Special Issue of Nanomaterials is focused on the continuing implementation of nanomaterials and nanostructures in the development of more sensitive and more specific sensing devices. As a result, these new devices employ smaller sensing elements and provide more "real time" capability. Often, the inclusion of nanomaterials leads to sensing elements for targets that were previously inaccess...

Novel Capping Agents for Nanomaterials

Nanomaterials are of great scientific interest as they bridge the gap between bulk materials and atomic or molecular structures. Capping agents are biological or chemical components naturally restrict the reaction and the particle growth in the nanoparticles synthesis. The understanding of the effect of capping on nanoparticles is one of the most important topics now-a-day. Protein and peptides...
