We demonstrate a label-free peptide-coated carbon nanotube-based immunosensor for the direct assay of human serum. A rheumatoid arthritis (RA)-specific (cyclic citrulline-containing) peptide, was immobilized to functionalized single-walled carbon nanotubes deposited on a quartz crystal microbalance (QCM) sensing crystal. Serum from RA patients was used to probe these nanotube-based sensors, and...

Over the recent years, numerical modelling and computer based simulation of the properties of carbon nanotubes have become the focal points of research in computational nano-science. In this paper, we present the computational studies about the mechanical and transport properties of armchair (4, 4) and zigzag (4, 0) single walled carbon nanotubes (SWCNT). Unlike other materials, carbon nanotube...

polycyclic aromatic hydrocarbons (such as, anthracene, benzo[a]pyrene and so on) are non-polar, hydrophobic compounds, which are not ionized. they are only slightly soluble in water. they are very dangerous compounds in the environment. the single-walled carbon nanotube (swnt) is used for removal and conversion of anthracene to low-risk products. in this study, electron transfer between anthrac...

a new hydroxylamine sensor has been fabricated by immobilizing oxadiazol denvative at the surface ol aglassy carbon electrode (gce) modified by multi-wall carbon nanotube (mivcnt). the adsorbed thin illms oroxadiazol derivative on the mwcnt modified gce show a pair of peaks with surface confined characierisnus.the oxadiazol derivative mwcni (omwcnt) modified gce shows highly catalytic activity ...

Carbon nanotubes have the potential to spur future development in electronics due to their unequalled electrical properties. In this article, we present a review on carbon nanotube-based circuits in terms of their electrical performance in two major directions: nanoelectronics and macroelectronics. In the nanoelectronics direction, we direct our discussion to the performance of aligned carbon n...

In silicon-based piezoresistive pressure sensor, the accuracy of sensor is affected mainly by thermal drift and sensitivity varies with rise in temperature. Here, temperature effects on desired representation are analysed. Use smart material Carbon nanotubes (CNT) a few effective compensation techniques presented this study to reduce effect sensor. Resistive employed extra piezoresistors Negati...
