Abstract:
With the emergence of avian flu, influence A virus and other diseases, the development of rapid, real-time, label-free biological sensors has become increasingly significant at the early detection and clinical diagnoses of various diseases. Single-walled carbon nanotubes (SWNTs) have unique one-dimensional structure, special electrical properties, good biocompatibility and size compatibility, so that the SWNTs have great potential uses in the biosensor fields due to these advantages. This article reviews recent examples of carbon nanotubes field-effect transistor (CNTFET) as a label-free biosensors for detecting a variety of biological macromolecules, such as protein, enzyme, DNA, cancer, virus, carbohydrate and so on.
