Patent number: 8580161Abstract: Photochromic materials that are useful for a variety of applications, including for making various unit functions of fluidic devices, particularly microfluidic devices, such as microchannels, valves and gates, using spiropyran materials, such as a polymeric composition comprising a spiropyran. In certain disclosed embodiments the spiropyran is admixed with a polymeric material. For example, the spiropyran may be intercalated into a polyalkylene or polyalkylene phthalate. The spiropyran also may be polymerized with at least one additional monomer to form a heteropolymer, such as by polymerization with styrene, styrene derivatives, acrylate and acrylate derivatives. The spiropyran compositions can be used to make, for example, a photoactuatable valve, a fluidic channel, etc. The valve may be associated with a microchannel, including photochromic microchannel. In certain disclosed embodiments, the valve, at least one microchannel, or both, are re-patternable by light exposure.Type: GrantFiled: May 4, 2011Date of Patent: November 12, 2013Assignee: State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State UniversityInventors: Vincent Thomas Remcho, Jintana Nammoonnoy, Myra Koesdjojo

Publication number: 20120292246Abstract: The present disclosure describes devices useful for microscale fluid purification, separation, and synthesis. Such devices generally comprise a fluid membrane that separates two or more fluids flowing through plural microchannels operatively associated with the membrane. Often, the membrane is a semipermeable membrane, such as might be used with a filtration device, such as a dialyzer. Devices of the present invention can be combined with other microscale devices to make systems. For example, the devices may be coupled with one or more microchemical microfactories, one or more micromixers, one or more microheaters, etc. Examples of devices made according to the present invention included an oxygenator, a dialyzer, microheat exchangers, etc.Type: ApplicationFiled: July 27, 2012Publication date: November 22, 2012Inventors: Goran Jovanovic, Sundar V.

Patent number: 8137554Abstract: The present disclosure describes devices useful for microscale fluid purification, separation, and synthesis devices. Generally, such devices comprise a fluid membrane that separates two or more fluids flowing through plural microchannels operatively associated with the membrane. The fluids can both be liquids, gases, or a liquid and a gas, such as may be used for gas absorption into a liquid. Often, the membrane is a semipermeable membrane, such as might be used with a filtration device, such as a dialyzer. Devices of the present invention can be combined with other microscale devices to make systems. For example, the devices may be coupled with one or more microchemical microfactories, one or more micromixers, one or more microheaters; etc. Examples of devices made according to the present invention included an oxygenator, a dialzyer, microheat exchangers, etc. Particular materials had to be developed for use with certain embodiments of the device disclosed herein.Type: GrantFiled: April 29, 2011Date of Patent: March 20, 2012Assignee: State of Oregon acting by and through the State Board of Higher Education on behalf of Oregon State UniversityInventors: Goran Jovanovic, Sundar V.

One embodiment of a disclosed apparatus comprises a laminated, microfluidic structure defining a reactor and a separator. Such apparatuses, or portions thereof, generally have dimensions ranging from about 1 micrometer to about 100 micrometers. To implement synthetic processes, disclosed embodiments of the apparatus generally include at least one valve, and often plural, selectively actuatable valves. Detectors, including optical detectors, also can be used to detect product and other materials as they flow by, or are otherwise presented to, the detector. Individual apparatuses may be coupled both in series and in parallel to form a system for making chemical compounds. The apparatus is particularly useful for making compounds requiring iterative reaction schemes, and further can be used to make compounds having morphological structures that resemble the morphology of the apparatus itself, such as dendrimers.Type: GrantFiled: March 21, 2005Date of Patent: March 24, 2009Assignee: State of Oregon Acting By and Through the State Board of Higher Education on behalf of Oregon State UniversityInventors: Chih-Hung Chang, Brian Kevin Paul, Vincent Thomas Remcho
