Pulsed thermionic emission from multiwalled carbon nanotube fibers has been demonstrated. From fibers with diameter of 150 μm we obtained an emission current of 16 μA at a repetition rate of 1 kHz. A comparison between our CNT fibers and a tungsten filament is also presented.
One of the major limitations in the development of ultrasensitive electrochemical biosensors based on one-dimensional nanostructure is the difficulty involved with reliably fabricating nanoelectrode arrays (NEAs). In previous work, a simple, robust and scalable wafer-scale fabrication method to produce multiplexed biosensors is introduced. Each sensor chip consists of nine individually addressable...
Dielectrophoresis (DEP) is an effective microelectronic technique for trapping and manipulating biological particles in a microfluidic environment, which relies on the highly asymmetric electric field gradient created by the microelectrodes. Here we demonstrate an AC DEP technique for single-bacteria trapping using nanoelectrode arrays (NEAs) in a "points-and-lid" configuration. The NEA...
A cell-to-cell fusion technique using 3-D microelectrodes array microchip has been developed. It permits cell-to-cell fusion operation in large amount simultaneously. And it needs much lower voltage (alternating voltage and pulse voltage) than the conventional cell fusion techniques. An array of 16 (4times4) microelectrodes can be fabricated on a 1times1cm silicon wafer. And an experimental system,...
