Note: The nanosensor  system  can be produced  on a large-scale CNT basis  using micro and mono layer construction techniques. Carbon nanomaterials have unique advantages, including  high surface-to-volume ratios, high electrical conductivity, chemical stability  , biocompatibility, and strong mechanical strength, so  they are often used as sensory elements. 

In  general, sensors based on carbon nanomaterials sensitivity  higher and lower detection limits than those   themselves. Carbon nanotechnology morphology is another important factor  in the design of nanochemical electrochemical sensors, which leads to an   increase in their capabilities and performance stability and improved electron transfer process   . Biosensors based on CNT carbon nanotubes are an efficient and important tool for detecting biological nano-molecules in the body and laboratory environments  . In fact, carbon nanotubes provide biocompatibility matrices for biosensors due to their  desirable properties  . Silica and carbon nanocomposite foam foams  can be used for detection Biological proteins are effective. Combination of carbon nanostructures  Due to  this structure, carbon nanotubes can be used to develop  glucose-sensitive sensors. Graphene, as a two-dimensional material, has a special place due to its unique physical properties  .

CNT single-walled carbon nanotubes consist of nested graphene layers and have a diameter of about 233 nanometers. The length of this nanotube can vary from a few nanometers to a micrometer. Adjustable chemical levels, high levels, unique physical properties and rhythmic length make mwCNTs an ideal choice for biomedical applications and the development of DNA electrochemical sensors. Nanotubes can usually be added to their masses to improve electrical properties in some materials, such as   carbon glass electrodes (GCE) , carbon paste  electrodes, graphite electrodes, or gold electrodes  . In general, the  addition of nanoparticles into the structure of the electrodes leads to  improved electrochemical properties, higher sensitivity, and less diagnostic limitations  . In addition, in diagnostic methods Electrochemically, the use of nanostructures generally  improves the charge transfer at the electrode surface.

Conclusion: 

The nanosensor  system  can be produced  on a large-scale CNT basis  using micro and mono layer construction techniques. Carbon nanomaterials have unique advantages, including  high surface-to-volume ratios, high electrical conductivity, chemical stability  , biocompatibility, and strong mechanical strength, so  they are often used as sensory elements.
