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.
Claims37
A laminate comprising a first substrate and a second substrate, which first substrate comprises a printed surface, which printed surface defines one or more microfluidic feature on the first substrate, which microfluidic feature comprises at least one cross-sectional dimension between about 0.1 μm and about 500 μm, wherein the second substrate forms a cover layer over the printed surface.
A method of forming a microfluidic laminate, the method comprising:
- (i) depositing a material on a first surface of a first substrate, which material defines one or more microfluidic features on the first surface, which microfluidic features comprise at least one cross-sectional dimension between about 0.1 μm and about 500 μm;
- (ii) covering the first surface with a second substrate, wherein the second substrate encloses the one or more microfluidic features.
