Estrela, P and Stewart, AG and Keighley, SD and Migliorato, P (2006) Biologically sensitive field-effect devices using polysilicon TFTs. Journal of the Korean Physical Society, 48. S22-S26. ISSN 0374-4884

The authors present a review of recent developments in the detection of biomolecular interactions with field-effect devices. Ion-sensitive field-effect transistors (ISFETs) and enzyme field-effect transistors (EnFETs), based on polycrystalline silicon (poly-Si) TFTs, are discussed. Label-free electrical detection of DNA hybridization has been achieved by a new method, by using MOS capacitors or poly-Si TFTs. In principle, the method can be extended to other chemical or biochemical systems, such as proteins and cells.
