  • Hydrophilic/hydrophobic surfaces
    Patent number: 7833486
    Abstract: A microfluidic device that comprises one or a plurality of microchannel structures each of which comprises a microconduit for transport and/or processing of liquid, the inner surface of which comprises a hydrophilic liquid contact surface area (surface area 1) that is delineated in at least one direction by a boundary to a hydrophobic surface area (surface area 2). The characteristic feature is that surface area 2 comprises a rough part that stretches along the boundary.

  • Fluidic functions based on non-wettable surfaces
    Publication number: 20050042770
    Abstract: A method for processing two or more liquid aliquots in a microchannnel structure of a microfluidic device. The microchannel structure comprises a hydrophilic microconduit with a fluidic function and a local non-wettable surface associated with the fluidic function/microconduit. Other aspects comprise a method for producing the fluidic function, which comprises introducing non-wettability on a local surface area S that is associated with the microconduit.
