Fluidic device containing 3d structures

Abstract

A micro fluidic device comprises a laminate structure, comprising a plurality of individual layers. At least one layer comprises a micro fluidic channel structure and at least on one side of said layer a further layer is arranged comprising a three-dimensional (3D) micro structure such that the 3D micro structure is influencing a flow characteristic of a fluid within the micro fluidic channel structure.

1 . A micro fluidic device comprising a laminate structure comprising a plurality of individual layers of which:
 a first layer comprises a micro fluidic channel structure, and   a second layer comprising a 3D micro structure configured to influence a flow characteristic of a fluid within the micro fluidic channel structure is provided adjacent said first layer, said 3D structure being formed from a structured pattern of an anisotropic material.   
     
     
         2 . The micro fluidic device of  claim 1 , wherein said 3D micro structure comprises projecting parts of the structured pattern of the anisotropic material erected out of a surface plane of said second layer. 
     
     
         3 . The micro fluidic device of  claim 1 , wherein said second layer has an increased thickness relative to said first layer. 
     
     
         4 . The micro fluidic device according to  claim 3 , wherein said 3D micro structure comprises holes formed by punching out said structured pattern from said second layer. 
     
     
         5 . The micro fluidic device of  claim 1 , further comprising a base layer and a top layer, at least one of the base layer and the top layer comprising an inlet opening and an outlet opening, each of the openings being in fluidic communication with said micro fluidic channel structure. 
     
     
         6 . The micro fluidic device of  claim 1 , wherein said second layer has different material properties on the opposite sides thereof. 
     
     
         7 . The micro fluidic device of  claim 1 , wherein said 3D micro structure comprises projecting parts erected out of a surface plane of said second layer, and detection dots provided at ends of said projecting parts, such that said detection dots provide confocal-optical detection within said micro fluidic channel structure.
