Patent number: 7344836Abstract: A method and apparatus designed for nucleic acid hybridization employs a hydrogen bond denaturation area with a higher temperature and a lower temperature nucleic acid hybridization area that is immobilized with nucleic acid probes. Nucleic acid-containing samples are introduced into the hydrogen bond denaturation area for heating curled nucleic acids in samples so that they become linear and are guided into the nucleic acid hybridization area. In this area, the nucleic acid hybridization rate can be multiplied by increasing the kinetic energy by the repeated flow of driven fluid. The nucleic acid hybridization apparatus provided by the invention contains a hydrogen bond denaturation area, a nucleic acid hybridization area, a two-way driving apparatus, and a temperature control element.Type: GrantFiled: August 12, 2004Date of Patent: March 18, 2008Assignee: Industrial Technology Research InstituteInventors: Yung-Chiang Chung, Yao-Sung Chang, Ming-Zheng Shiu

Publication number: 20040091366Abstract: A pneumatic driving device and the associated method for micro fluids, wherein the pneumatic driving device for micro fluids is constructed by connecting a fluid pipe with a structure that is formed by two gas stream inlets, a gas stream fender, a gas stream flow path and a gas stream outlet. The suction, exclusion and stagnation for the micro fluids inside the fluid pipes can be accomplished by adjusting the flow rates of the gas streams into the device at the two gas stream inlets. In the invention, several pneumatic driving devices are connected to form a single recursive pneumatic driving device by the concept of recursion, and the micro fluids inside several fluid pipes can be controlled to mix or to separate through the recursive pneumatic driving device by adjusting the flow rates of the gas streams into the device at different gas stream inlets.Type: ApplicationFiled: November 10, 2003Publication date: May 13, 2004Applicant: Industrial Technology Research InstituteInventors: Yung-Chiang Chung, Te-Chun Wu, Yuan-Fong Kuo, Shr-Hau Huang

Patent number: 6331073Abstract: An order-changing microfluid mixer comprises an extended microfluidic channel and a chamber structure that provides order-changing functions to microfluid when the microfluid passes through the chanter structure. The order-changing chamber has two openings connected to said microfluidic channel and divides said microfluidic channel into two sections. When a microfluid is driven from one section of the microfluidic channel to the other, the microfluid enters into the order-changing chamber and flows along a first side of the order-changing chamber, whereby portions of the microfluid positioned adjacent to the second side of the order-changing chamber remain unmoved.Type: GrantFiled: October 20, 2000Date of Patent: December 18, 2001Assignee: Industrial Technology Research InstituteInventor: Yung-Chiang Chung
