Abstract :
We present the design, development and analysis of electromagnetic microwave resonant carbon nanotube bio-sensors. These bio-sensing sensors consist of circular disk electromagnetic resonant circuits coated with single and multi walled carbon nanotubes (SWNTs and MWNTs) that are highly sensitive to adsorbed bio-molecules. The principle operation of these sensors is based on the changes of resonant frequency when the carbon nanotube interface is exposed to bio-materials. Our initial experimental results demonstrate that resonant frequency of the carbon nanotube resonator sensors changes 2 MHz upon exposure to Isopropanol.
