Patent ID: 8057629

Claim:
A method of making a laminated, polymeric microfluidic structure, comprising: providing a first component having first and second surfaces, wherein at least one of the surfaces includes a microstructure, further wherein the first component is a polymeric material; providing at least a second, polymeric component having first and second surfaces, wherein one of the first and second surface of the first component is intended to be fixedly attached to a respective second and first opposing surface of the second component; applying a weak solvent bonding agent with respect to the polymeric components to at least one of the first and the second component at a first temperature; creating a thermal activation condition by raising the temperature to a second temperature that is greater than the first temperature for thermally activating the weak solvent; and adjacently contacting the opposing surfaces, wherein the weak solvent has a chemical formula of at least one of: where, R 1 =H or R, where R=alkyl, R 2 =H or R, where R=alkyl, and R 3 =H or R, where R=alkyl; where, R 1 =H or R, where R=alkyl, and R 2 =H or R, where R=alkyl; and where, R 1 =H or R, where R=alkyl.
