Abstract:Single-Walled Carbon Nanotubes (SWNTs) are reported to be very sensitive to numerous odors and could serve as the next generation of miniature gas sensors. Recently, we have shown that SWNTs functionalized with DNA hold even greater promise than bare SWNTs as high sensitivity gas sensors. The DNA-decorated SWNT gas sensors were integrated on CMOS circuitry with built-in amplifiers. In the paper, we report on the performance of the nanosensors as a function of the DNA sequence used for adsorption on SWNTs. A di… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
