In nanosensors, the interaction of electron nanoparticles with graphene is  absorbed, which changes the electrical conductivity  at the surface of graphene nanosensors. Absorption of  small amounts of nanoelectrons  with very low molecular weight movement has changed the resistance of nano-graphene  , which is proportional to the concentration in the nano-graphene sensors. Different molecular conditions cause different changes in graphene resistance,  which often  affects the electron  or  electrophoresis of graphene at the nanoscale Because the noise level in graphene is low. Limitations of identification  with these nanostructures are higher and less sensitive  The repeatability of these nanostructures  in sensor production is less than graphene and  carbon nanotubes.

Graphene sensors with nanotechnology offer new solutions in the field of physical, chemical and biological measurement that increase sensitivity in diagnosis, feature, multiplication and portability for different types of assessments, safety and environmental . If there is a need for carbon nanotubes or  pure graphene to build the sensor,  the CVD growth method is the best choice. Making  nanotubes and carbon nanotubes with metals or metal  oxides is a practical way to increase  sensitivity and minimize side effects  Various properties of  carbon nanotubes, such as increased interaction with large molecules,  can increase the efficiency of graphene nanofibers  , as well as noise levels. Reduces graphene nanoparticles and increases the sensitivity of the sensor   to low values ​​of the target molecule.

Conclusion : 

The unique electronic properties and structure of carbon nanotubes, such as recycled nanotubes, graphene and graphene oxide, are  used to make nanosensors.
