Electroosmotic pump patent approved in Sweden

posted Nov 1, 2011, 11:34 AM by Nathaniel Robinson
Lunavation has been granted a Swedish patent (SE 534 488 C2) for an electroosmotic pump invented at Linköping University.

The pump, which has a wide range of applications including point-of-care medical diagnostics and microfluidic chemical and biological systems, has several distinct advantages:
  • Wide voltage range - the pump has been tested to work with simple DC voltages ranging from below 2 V to over 15o V.  This means that the pump can be operated by batteries in small, portable devices without requiring sophisticated electronics to drive it.
  • Easily manufactured - the materials in the pump are solution processable, meaning that devices can be made with relatively inexpensive processes such as inkjet printing.
  • No electrolysis - the device eliminates or minimizes the electrolysis of solvent, meaning that the production of gas bubbles or acid, base and peroxide are avoided.  This allows the device to safely handle sensitive chemical and biological samples such as blood or proteins.
