Title:
Current correlation functions for chemical sensors based on DNA decorated carbon nanotube

Authors:
Poonam, P; Deo, N

Author Full Names:
Poonam, P.; Deo, N.

Source:
SENSORS AND ACTUATORS B-CHEMICAL 135 (1): 327-335 DEC 10 2008

Language:
English

Document Type:
Article

Author Keywords:
Carbon nanotube; DNA; Correlation functions; Chemical sensor; Sequence detector

Abstract:
The current characteristics of DNA decorated carbon nanotubes for different gas odors are studied. A simple model of charge transfer between the Gas-DNA-base complex and single wall carbon nanotube (SWCN) is proposed to explain the current response for different odors. The autocorrelation and two-point correlation functions are calculated for the Current sensitivity curves. These correlation functions together with the Current characteristics form finger-prints for detection of the odor and DNA sequence. (C) 2008 Elsevier B.V. All rights reserved.

Title:
Selective diameter uptake of single-walled carbon nanotubes in water using phosphonated calixarenes and 'extended arm' sulfonated calixarenes

Abstract:
Single-walled carbon nanotubes (SWCNTs) have been successfully solubilized using water-soluble p-phosphonated calix[n] arenes (n = 4, 6, 8) and 'extended arm' upper rim functionalized (benzyl, phenyl) p-sulfonated calix[8] arenes. Selective SWCNT diameter solubilization has been demonstrated and subsequent preferential enrichment of SWCNTs with semiconducting or metallic electronic properties has been achieved. These water-soluble supramolecular systems can be incorporated into post-growth purification protocols with direct implications in areas such as nano-electronics and device fabrication.
