An electronic device, namely suspended gate thin film transistor (SGTFT), for rapid and direct detection of specific DNA sequences with high sensitivity is presented. It is an usual P-type polysilicon TFT where the gate contact is a Si3N4/polysilicon/Si 3N4 bridge suspended at 0.5 mum above the SiO 2/Si3N4 gate insulator. The high field effect due to the low height of the gap induces high sensitivity...
Microsystems' including biomolecules is currently a research field in fast development and expansion. By coupling biomolecules to non-biological electronic transducers, molecular bioelectronic systems could one day be used in a wide variety of applications, including biosensors, biofuel cells and maybe even biocomputers. A major thrust in this framework is to integrate and process the chemical information...
