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.
