Direct electrical detection of DNA synthesis

A System for Multiplexed Direct Electrical Detection of DNA Synthesis.

An electronic system for the multiplexed detection of DNA polymerization is designed and characterized. DNA polymerization is detected by the measurement of small transient currents arising from ion diffusion during polymerization. A transimpedance amplifier is used to detect these small currents; we implemented a twenty-four channel recording system on a single printed circuit board. Various c...

Direct Ultrasensitive Electrical Detection of DNA and DNA Sequence Variations Using Nanowire Nanosensors

The development of electrically addressable, label-free detectors for DNA and other biological macromolecules has the potential to impact basic biological research as well as screening in medical and bioterrorism applications. Here we report two-terminal silicon nanowire electronic devices that function as ultrasensitive and selective detectors of DNA. The surfaces of the silicon nanowire devic...

Electrical Detection of Dna Binding Proteins

The base pair stack of double helical DNA has proven to be an effective medium for charge transport. The π-stacked DNA base pairs can mediate charge transport (CT) chemistry over distances as long as 20 nm, and the reaction is exquisitely sensitive to DNA sequence-dependent conformation and dynamics. This sensitivity to perturbations in DNA structure and base pair stacking makes DNA-mediated ch...
