Abstract:

The biosensors exhibit many advantages such as simple operation， rapid reaction and high sensitivity in pathogen detection. The sensitivity and specificity of the biosensors can be significantly enhanced by the combined use of carbon nano-materials（such as carbon nanotubes and graphene） and bio-sensing devices. This paper reviews the characteristics of carbon nano-biosensors， its applications in pathogen detection and new development.

Key words: Graphene, Carbon nanotube, Immunosensor, Pathogen detection
