PORÖSES MIKROVENTIL
Microfluidic devices having porous materials that restrict fluid flow rate for a given pressure are provided. Multiple porous regions can be constructed in a single device so that they have different valving capabilities or impedances, and in unison can control the overall direction of fluid flow. P...

| description | Microfluidic devices having porous materials that restrict fluid flow rate for a given pressure are provided. Multiple porous regions can be constructed in a single device so that they have different valving capabilities or impedances, and in unison can control the overall direction of fluid flow. Porous regions can be constructed in various ways, such as, for example: by inserting porous materials into or between channels; by sandwiching one or more sheets or layers of porous materials between other layers of a device; or by inserting a liquid, solution, slurry, or suspension into a microfluidic channel and then permitting the formation of porous deposits by promoting at least partial evaporation. Adhesive tape may be used for one or more layers of such a microfluidic device. |
