| Research Abstract |
The electrical sensing of deoxyribonucleic acid hybridization by capacitance-voltage measurements of metal/micro-gap/insulator/semiconductor structure devices has been demonstrated. The hybridization of deoxyribonucleic acid has been characterized from the shift of the capacitance-voltage curve for the sensing device. It has been demonstrated that a metal/micro-gap/insulator/semiconductor structure device can distinguish between deoxyribonucleic acid hybridization and un-hybridization. The electrical sensing operation of pure water by capacitance-voltage measurements of a metal/micro-gap/insulator/semiconductor array has been demonstrated.
