| 20090239033 | DIAPHRAGM AND DEVICE FOR MEASURING CELLULAR POTENTIAL USING THE SAME, MANUFACTURING METHOD OF THE DIAPHRAGM - A diaphragm is formed by etching a substrate. This substrate has a first surface provided with a depression by isotropic dry etching, and a second surface opposite the first surface. Furthermore, a through-hole is formed from the depression to the second surface by anisotropic dry etching. The depression and the through-hole are formed by using one resist mask. The depression has a hemispherical shape or a semi-elliptical spherical shape. | 09-24-2009 |
| 20100126922 | COMPONENT SEPARATION DEVICE - A component separating device includes a flow channel, an acoustic wave generator for generating an acoustic wave in the flow channel, a first inlet channel for introducing a fist solution containing solid particles into the flow channel, a second inlet channel for introducing a second solution, and outlet channels for discharging a solution from the flow channel. A density grade generator is provided at the first inlet channel for forming a density grade of the solid particles. This component separating device extracts the solid particles into a high-purity solution at a high collecting rate. | 05-27-2010 |
| 20100170790 | BIOSENSOR - A sensor includes a diaphragm having a through-hole ( | 07-08-2010 |
| 20100203621 | BIOSENSOR - A biosensor has the following elements: a diaphragm having a through-hole; a frame supporting the diaphragm and having a cavity; and pillars formed on the side of inner wall surface of the frame and on the surface of the diaphragm. This structure can suppress the occurrence of bubbles in the vicinity of the through-hole, and easily remove the remaining bubbles. Thus the measuring reliability of the biosensor can be improved. | 08-12-2010 |

| 20110111984 | SEQUENCER - A sequencer that measures a nucleic acid sequence in a nucleic acid strand includes: a base material having a surface made of silicon; and a fibrous protrusion that is made of silicon dioxide and is directly joined to the surface of the base material made of silicon, wherein a plurality of the nucleic acid strands are fixed onto the fibrous protrusion. | 05-12-2011 |
| 20110120864 | CELLULAR ELECTROPHYSIOLOGY SENSOR CHIP AND CELLULAR ELECTROPHYSIOLOGY SENSOR USING THE CHIP, AND METHOD OF MANUFACTURING CELLULAR ELECTROPHYSIOLOGY SENSOR CHIP - A cellular electrophysiology sensor is adapted to measure an electrical change of a test cell. A chip for the sensor includes a diaphragm, and a thermally-oxidized film mainly containing silicon dioxide on the diaphragm. The diaphragm includes a silicon layer and a silicon dioxide layer on an upper surface of the silicon layer. A through-hole passing through the silicon layer and the silicon dioxide layer is formed. The through-hole has an opening which opens at the silicon dioxide layer and is adapted to capture the test cell. The thermally-oxidized film is provided on an inner wall surface of the through-hole, and unified with the silicon dioxide layer at the opening of the through-hole. This cellular electrophysiology sensor chip can stably capture the test cell and provides a gigaseal stably even if test cells have different properties, | 05-26-2011 |
| 20110126590 | PROCESS FOR PRODUCING CELL ELECTROPHYSIOLOGICAL SENSOR AND APPARATUS FOR PRODUCING THE CELL ELECTROPHYSIOLOGICAL SENSOR - A process including holding sensor chip; holding glass tube surrounding the outer periphery of the side surface of sensor chip; applying a wind pressure to the side surface of glass tube from the outside of glass tube and melting glass tube to be glass-welded to the side surface of sensor chip. Thereby, the outer periphery of sensor chip can be surrounded by a highly hydrophilic glass tube. Thus, a cell electrophysiological sensor with high measurement accuracy can be produced. | 06-02-2011 |
