RNA Functionalized Carbon Nanotube for Chemical Sensing
نویسندگان
چکیده
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 ssRNAfunctionalized SWNT-FETs promising building blocks in developing large arrays of sensors for electronic olfaction and disease diagnosis.

متن کاملModifying functionalized-carbon-nanotube capacity to enhance water-vapor adsorption capacity from nitrogen gas
The primary objective of this paper is to enhance the water-vapor-adsorption capacity of multiwall-carbon-nanotube (MWCNT) from nitrogen gas by grafting sulfonic acid groups and doping palladium nanoparticles into the adsorbent. MWCNT has been selected to be modified because of having homogeneous adsorption energy compared to silica gel. As a result, it is capable of creating isotherm having sh...
