Abstract:
The invention relates to a microfluidic device comprising: a substrate provided with a fluid channel; a plurality of electro osmotic flow drive sections for providing electro osmotic flow in the channel, each drive section comprising electric field electrodes, exposed to the channel, and one or more gate electrodes, separated from the channel by an insulating layer, and control means connected to said electrodes of each drive section so as to control the direction of the electro osmotic flow in the channel.
Abstract:
A method for nano-scale high resolution patterning of self-assembled monolayer using soft X-rays is provided. The method involves forming an aromatic imine molecular layer having substituents at its terminal rings on a substrate, selectively cleaving bonds to the subsituents of the aromatic imine molecular layer, and hydrolyzing the aromatic imine molecular layer
Abstract:
The disclosed sensor chip (120) includes a substrate (126) and a moving member (132) coupled to the substrate and disposed for movement relative to the substrate. The moving member (132) moves relative to the substrate in a first direction and in a second direction in response to movement of the substrate. The first direction is different than the second direction. The moving member includes a plurality of receptors (140). The receptors are configured for selectively binding to a first measurement.
Abstract:
The present invention is directed to a substrate having a plurality of microfeatures that provide a high surface area and are open to provide ready access to fluids and components therein. Methods of making the high surface area substrates are described and include generating microfeatures and/or microstructures on the surface of the substrate.

Abstract:
The invention relates to providing a columnar structure having a uniform shape and excellent heat resistance and mechanical strength that is formed on a substrate of silicon, a method of preparing the structure, and a DNA separation device prepared by the method. The structure has, on a substrate (11) made of silicon, columns (12) the main surface of which is covered with a thermally oxidized film (16). The columns (12) are made of the thermally oxidized film (16) only or of the thermally oxidized film (16) and silicon. The thermally oxidized film formed on the columns (12) is connected to those formed on the surface or inside of the substrate (11).

The present invention is directed to the use of deposited thin films for chemical or biological analysis. The invention further relates to the use of these thin films in separation adherence and detection of chemical of biological samples. Applications of these thin films include desorption-ionization mass spectroscopy, electrical contacts for organic thin films and molecules, optical coupling of light energy for analysis, biological materials manipulation, chromatographic separation, head space adsorbance media, media for atomic molecular adsorbance or attachment, and substrates for cell attachment.
Abstract:
The present invention relates to a method of producing a gas sensor co-acting detector intended for the detection of electromagnetic waves, such as infrared light rays, that pass through a gas cell. The gas cell (2) includes a cavity (21), which functions to enclose a gas volume (G) for measuring of evaluating purposes. The surface or parts of the surface forming walls within the gas cell or the cavity is/are coated with one or more different metal layers (M1, M2) with the intention of providing a highly reflective surface for reflection of said electromagnetic waves. The detector (3) is comprised of a thermal element and is formed on a base structure (31). That part of the base structure that shall form said detector is comprised of one or more topographically structured surface regions. At least said surface region or surface regions is/are coated with a first and a second electrically conductive metal layer (M1 and M2 respectively) which are intended to form said thermocouple. The first metal layer (M1) is applied at a first angle other than 90°, and the second metal layer (M2) is applied at a second angle which is also other than 90° and which differs from the first angle. The topographical structure and/or configuration including the thus coated electrically conductive layers provides the function of one or more thermocouples, by virtue of the first and the second metal layers (M1, M2) overlapping each other within discrete detector-associated surface parts.
