20090208372 | SHEATH FLOW DEVICE AND METHOD - A sheath flow system having a channel with at least one fluid transporting structure located in the top and bottom surfaces situated so as to transport the sheath fluid laterally across the channel to provide sheath fluid fully surrounding the core solution. At the point of introduction into the channel, the sheath fluid and core solutions flow side by side within the channel or the core solution may be bounded on either side by the sheath fluid. The system is functional over a broad channel size range and with liquids of high or low viscosity. The design can be readily incorporated into microfluidic chips without the need for special manufacturing protocols. | 08-20-2009 |
20140017149 | Sheath flow method and apparatus for laminar flow systems - A sheath flow system having a channel with first and second fluid transporting structures located on opposing surfaces facing one another across the channel in the top and bottom surfaces of the channel situated so as to transport the sheath fluid laterally across the channel to provide sheath fluid fully surrounding the core solution. At the point of introduction into the channel, the sheath fluid and core solutions flow side by side within the channel or the core solution may be bounded on either side by the sheath fluid. The system is functional over a broad channel size range and with liquids of high or low viscosity. The design can be readily incorporated into microfluidic chips without the need for special manufacturing protocols | 01-16-2014 |
20140087466 | MICRO BLOOD VESSELS AND TISSUE DUCTS - A fiber includes one or more layers of polymer surrounding a central lumen, and living animal cells disposed within the lumen and/or within at least one of the one or more layers, wherein the fiber has an outer diameter of between 5 and 8000 microns and wherein each individual layer of polymer has a thickness of between 0.1 and 250 microns. Also disclosed are model tissues including such fibers, and method of making such fibers. The fibers can serve as synthetic blood vessels, ducts, or nerves. | 03-27-2014 |
