Efficient Control of Dna Transport in Nanopore-based Nanofluidic Transistors

Nanofluidic transistors (NFTs), composed of solid-state nanopores with an electrically controlled embedded gate electrode, promise exciting new ways to build chemical and biological circuits that can be used in drug-delivery and lab-on-a-chip systems. However, the reliable fabrication of sub-10nm gated nanopores and control over biomolecule capture and transport has been challenging. Herein, we...

Silicon-on-insulator based nanopore cavity arrays for lipid membrane investigation.

We present the fabrication and characterization of nanopore microcavities for the investigation of transport processes in suspended lipid membranes. The cavities are situated below the surface of silicon-on-insulator (SOI) substrates. Single cavities and large area arrays were prepared using high resolution electron-beam lithography in combination with reactive ion etching (RIE) and wet chemica...

Field-effect reconfigurable nanofluidic ionic diodes.

Several types of nanofluidic devices based on nanopores and nanochannels have been reported to yield ionic current rectification, with the aim to control the delivery of chemical species in integrated systems. However, the rectifying properties obtained by existing approaches cannot be altered once the devices are made. It would be desirable to have the ability to modulate the predefined proper...

Designing light-emitting diode arrays for uniform near-field irradiance.

We analyze the first-order design of light sources consisting of multiple light-emitting diodes (LEDs) to uniformly illuminate a near target plane by considering each single LED as an imperfect Lambertian emitter. Simple approximate equations and formulas are derived for the optimum LED-to-LED spacing, i.e., the optimum packaging density, of several array configurations to achieve uniform near-...
