Publication number: 20240123405Abstract: A solid type nano-pore sequencer is arrayed easily. In a liquid column separation device including first and second base materials, a liquid feeding unit supplies fluids to a gap between the two base materials. Hydrophilic and hydrophobic regions are disposed on a surface of the second base material, and the hydrophilic region is disposed to oppose a predetermined position of the first base material where a substance to be measured is made to pass through. Also, a flow passage space includes at least one inlet and outlet through which fluids can flow in and out. A representative length of the hydrophilic region is made larger than a distance between the first and second base materials, and thereby a liquid column capable of connecting the first base material and the second base material is formed by making two or more immiscible fluids to flow by the liquid feed unit.Type: ApplicationFiled: February 17, 2021Publication date: April 18, 2024Inventors: Ruochi HSU, Kei TAKENAKA, Michiru FUJIOKA, Nobuhiro TSUKADA, Yohei HANAZAKI, Nobuaki YOSHIOKA

Patent number: 9433883Abstract: The present invention provides an impaction-based microorganism collecting device in which microorganisms are captured by the capture surface of a collection plate. The microorganism collecting device is designed to reduce the influence of the lateral wind flowing over the perforated plate having multiple nozzles and also prevent warpage of the perforated plate. Multiple air vents are formed around the circumference of the capture surface and through the capture surface so that air that has flowed through the nozzles of the perforated plate onto the capture surface can be discharged. This allows the air to flow in multiple directions over the capture surface, thereby reducing the speed of the air and increasing the microorganism capture rate.Type: GrantFiled: February 22, 2011Date of Patent: September 6, 2016Assignee: Hitachi, Ltd.Inventors: Kei Takenaka, Yasuhiko Sasaki, Shigenori Togashi
