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...
In this paper, we demonstrate the integration of single-stranded-DNA (ss-DNA) decorated single-walled carbon nanotubes (SWNT) onto complementary metal oxide semiconductor (CMOS) circuitry for gas sensing applications. Utilizing dielectrophoresis (DEP) assembly, a simple and a low temperature process, we first demonstrate integration of SWNTs onto CMOS circuitry at the die level. SWNTs are sensitive...
