The detection of biological events is crucial in many life science applications such as disease diagnosis and the analysis of biological systems. Song Liu and Xuefeng Guo from the Beijing National Laboratory for Molecular Sciences and Peking University now review the use of field-effect transistors (FET) based on carbon nanomaterials for biosensing applications. Biosensors made from graphene or carbon nanotubes-based FETs have several advantages. They are very sensitive to environmental parameters such as surface charges or pH values. Furthermore, these nanostructures are very good charge conductors, allowing for a fast response to external changes. In particular sensors based on transistor geometries are of benefit, as biological reactions taking place at their surface directly influence the charge transport through the device. Although reliability remains an issue, such carbon-derived biosensors have already shown protein reactions and detection down to the single molecule level, clearly establishing their potential for practical applications.
