Abstract:
1. A method for preparing a microfluidic channel ( 6 ) with shifted levels, wherein said microfluidic channel ( 6 ) with shifted levels connects a channel ( 4 a , 4 b ), situated in a first level of a base plate ( 1 , 11 ) containing a microfluidic system, with a second level of said base plate ( 1 , 11 ), by emerging from the first level of the base plate ( 1 , 11 ), wherein said microfluidic channel ( 6 ) with shifted levels comprises channel pillar(s) ( 2 a , 2 b ) and a channel bridge ( 3 ), comprising: creating a longitudinal edgeless hollow, as a channel pillar ( slicing off the portion of the base plate ( inserting a patterning profile-piece which is made of a removable material and has a cross-section that fits into an orifice created at the section of the channel pillar ( filling-up the base plate ( solidifying the filling-up material ( then removing the patterning profile-piece with a chemical or a physical process.
