Biosensors using field-effect transistors show great promise

Researchers review scientific advances of electrolyte-gated carbon nanotube field-effect transistor biosensors, which are characterized by superior electronic properties and intrinsic signal amplification and are capable of detecting a wide range of biomolecules with high sensitivity. One of their main components is the biorecognition element, which selectively recognizes the analyte of interest. Biotransduction devices convert the interaction between the biorecognition element and analyte into a measurable signal.
