Chemiluminescence on a Microchip.

Influence of silicon membrane interposed between glass plates on microchip capillary electrophoresis with a chemiluminescence detector.

Integrated multilayer flow system on a microchip.

We utilized microchip technology and found that the multilayer flow of liquids can be formed in microchannels. Liquid/liquid interfaces were formed parallel to the side wall of the microchannels, because the surface tension and friction force are stronger than the force of gravity. A water/ethylacetate/water interface was formed in a 70-microm-wide and 30-microm-deep channel. The interface was ...

Artificial Alveolar-Capillary Membrane on a Microchip

Tunable superluminal propagation on a silicon microchip.

We demonstrate tunable superluminal propagation in a silicon microphotonic device in a solid-state room-temperature device of tens of micrometers in dimension allowing easy integration with high-bandwidth room-temperature systems. We achieve tunable negative delays up to 85 ps and effective group indices tunable between -1158 and -312.

Analysis of plasmid samples on a microchip.

We have developed a LabChip-based plasmid assay that runs on the Agilent 2100 Bioanalyzer. The assay determines the sizes and relative concentrations of the multiple forms of plasmid samples. Twelve samples can be analyzed on each chip in an automated run lasting approximately 30min. By using a supercoiled DNA sizing standard of 2-16kb, the size of the analyzed plasmid can be determined. The re...
