Abstract

We study the odor response characteristics of DNA decorated carbon nanotubes for different gas odors in the experiment carried out in NANO LETTERS Vol. 5, No. 9, 1774-1778 (2005), by Cristian Staii, Alan T. Johnson, Jr., Michelle Chen, Alan Gelperin. For different gas odors and DNA sequences, different characteristic patterns have been observed by calculating the fluctuations in the current (the autocorrelation and two point correlation functions). We also explain the sequence dependent odor response of the ss-DNA/SWCN-FET sensor.
