Abstract:
1. A process for preparing a microfluidic device using a conventional printer, the process comprising: providing a first substrate and a second substrate; applying a conductive thin film on the second substrate; applying a solid adhesive thin film sheet to the first substrate and to the conductive thin film on the second substrate, respectively; printing a wax ink masking layer on the solid adhesive thin film sheet of the first substrate and on the solid adhesive thin film sheet of the second substrate, respectively, using the conventional printer; selectively etching the solid adhesive thin film sheet on the first substrate to form a desired pattern, and selectively etching the solid adhesive thin film sheet and the conductive thin film on the second substrate to form a desired pattern, respectively, wherein etchants that etch the conductive thin film and the solid adhesive thin film sheets without reacting with the wax ink are used to etch the solid adhesive thin film sheets and the conductive thin film; removing the wax ink masking layer from the first substrate and the second substrate, respectively; aligning and bonding together the pattern on the solid adhesive thin film sheet of the first substrate to the pattern on the solid adhesive thin film sheet of the second substrate; and curing the solid adhesive thin film sheets of the bonded first substrate and second substrate to result in the microfluidic device.
