Restriction mapping in nanofluidic devices.

We have performed restriction mapping of DNA molecules using restriction endonucleases in nanochannels with diameters of 100-200 nm. The location of the restriction reaction within the device is controlled by electrophoresis and diffusion of Mg2+ and EDTA. We have successfully used the restriction enzymes SmaI, SacI, and PacI, and have been able to measure the positions of restriction sites wit...

Conductivity-based detection techniques in nanofluidic devices.

This review covers conductivity detection in fabricated nanochannels and nanopores. Improvements in nanoscale sensing are a direct result of advances in fabrication techniques, which produce devices with channels and pores with reproducible dimensions and in a variety of materials. Analytes of interest are detected by measuring changes in conductance as the analyte accumulates in the channel or...

Applications of Nanofluidic Devices in Chemistry

page 124 Abstract: Nanofluidic channels have many uses in the chemical field, including site specific combinatorial synthesis, macroand bio-molecular analysis, and other “lab on a chip” applications. The objective of this research is to fabricate arrays of nanochannels designed to facilitate the transport of aqueous ionic solutions by adapting a form of the nanoimprinting technique. Nanoimprint...

Direct optical mapping of transcription factor binding sites on field-stretched λ-DNA in nanofluidic devices

Mapping transcription factor (TF) binding sites along a DNA backbone is crucial in understanding the regulatory circuits that control cellular processes. Here, we deployed a method adopting bioconjugation, nanofluidic confinement and fluorescence single molecule imaging for direct mapping of TF (RNA polymerase) binding sites on field-stretched single DNA molecules. Using this method, we have ma...
