Abstract: | We present an electronic sensor in the molecular scale, which is very sensitive for detection and sensing of DNA characteristics and DNA activities in particular activities between DNA duplex and any protein. Here, the device shows that DNA is electronically inserted to be on the same time as an electrical device transducer and as a biological target in a carbon nanotube-DNA-carbon nanotube electronic sensor. We have performed a DNA binding through an amide group by the electron transfer through amide group. The presented device has shown an efficient and rapid procedure to bind the electrical vulnerability of DNA with the detection of enzymatic effectiveness leading to high efficient biosensor. |
