Abstract

We demonstrate a versatile class of nanoscale chemical sensors based on single stranded RNAs (ssRNAs) as the chemical recognition sites and single-walled carbon nanotube field effect transistors (SWNT-FETs) as the electronic readout components. The sensor responses differ in sign and magnitude depending on both the type of gaseous analyte and the sequence of ssRNA being used. Such rapid response, sensitivity to large variety of analytes, self-regenerating ability, and reproducibility make ssRNA-functionalized SWNT-FETs promising building blocks in developing large arrays of sensors for electronic olfaction and disease diagnosis.
