1. A laminate comprising:
- a first surface comprising a first planar section;
a second surface comprising a second planar section;
an intermediate printed layer on at least one of the first and second planar sections, the intermediate printed layer disposed between the first and second planar sections, the intermediate printed layer defining first and second walls of at least a first microscale channel, which microscale channel comprises at least one cross-sectional dimension between about 0.1 μ
m and about 500 μ
m, the channel comprising the walls formed by the intermediate printed layer, a portion of the first planar section and a portion of the second planar section.

Abstract
Laminates having microfluidic structures disposed between sheets of the laminate are provided. The microfluidic structures are raised on a sheet of laminate, typically by printing the structure on the sheet. Printing methods include Serigraph, ink-jet, intaligo, offset printing and thermal laser printing.

23. A method of forming a channel between two surfaces, the method comprising:
-
providing a first surface comprising a first planar section; providing a second surface comprising a second planar section;
applying a first channel comprising a first and a second wall to the first or second planar section by a process comprising applying a printed layer comprising at least a portion of the first or second wall on the first or second planar substrate, wherein the first and second walls are raised in comparison to the first or second planar surfaces, and wherein the first channel comprises at least one cross-sectional diameter between about 0.1 μ
m and 500 μ
m; and
,bonding the first and second planar sections, wherein the first channel is in contact with a portion of the first planar section and a portion of the second planar section. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
