The thesis necessity Owing to the unique properties such as larger surface area high conductivity high mechanical stability excellent electronic mobility inert chemical properties in solution and high compatible biological properties . carbon nanotubes CNTs and graphene materials are promising to apply in many other fields such as electronics energy and fabrication of ultra-small sensors. In particular field effect transistor FET and especially ion sensitive field effect transistor ISFET using CNTs graphene are showed that they have high sensitivity quick response time and very low detection limit. This is because the CNTs graphene material in the sensor is in direct contact with the analytical material and directly convert the biological reactions on the electrode surface into electrical signals. Therefore a small change of analytical material could be detected. Some of the sensors based on FET and ISFET configurations using CNTs and graphene materials have been launched in the detection of certain substances such as glucose DNA atrazine etc. In order to improve the potential .
