Field-effect-based DNA sensors

Summary of field-effect-based DNA sensors reported in literature... [Pg.214]

Y. Han, A. Offenhauser, and S. Ingebrandt, Detection of DNA hybridisation by a field-effect based sensor with covalently attached catcher molecules. Surf. Interface Anal. 38, 176-181 (2006). [Pg.233]

Carbon nanotubes, especially SWNTs, with their fascinating electrical properties, dimensional proximity to biomacromolecules (e.g., DNA of 1 nm in size), and high sensitivity to surrounding environments, are ideal components in biosensors not only as electrodes for signal transmission but also as detectors for sensing biomolecules and biospecies. In terms of configuration and detection mechanism, biosensors based on carbon nanotubes may be divided into two categories electrochemical sensors and field effect transistor (FET) sensors. Since a number of recent reviews on the former have been published,6,62,63 our focus here is mostly on FET sensors. [Pg.209]

Actually, special attention is paid in the application of biosensors in environmental analysis. The high cost and slow turnaround times typically associated with the measurement of regulated pollutants clearly indicates a need for environmental screening and monitoring methods that are fast, portable and cost-effective. To meet this need, a variety of field analytical methods have been introduced. Because of their unique characteristics, however, technologies such as DNA sensors and immunosensors based on AuNPs might be exploited to fill specific niche applications in the environmental monitoring area. [Pg.955]

Other examples of CMOS-based field-effect sensor arrays are used for the monitoring of extracellular electroph iological signals or pH changes [56]. Those devices normally involve only ISFETs and hence are less complicated in structure than those required for DNA or protein arrays. [Pg.198]

A large number of biosensors are based on modified versions of field-effect transistors (FETs), and in combination with silicon nanowires (SiNWs) they form versatile, label-free sensors that have been used for the detection of proteins, single viruses, and DNA [6-11]. [Pg.117]
