Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS URBANA, ILLINOIS
Field: Chemical engineering (Chemistry)
Classification: CPC B | IPC B

Claim 0:
1. A microfluidic diagnostic device with a three-dimensional (3D) flow architecture, the microfluidic diagnostic device comprising:
a polymeric body having first and second external opposing surfaces and comprising:
first flow channels in the first external opposing surface;
second flow channels in the second external opposing surface; and
connecting flow passages extending through a thickness of the polymeric body to connect the first flow channels to the second flow channels, thereby defining a continuous 3D flow pathway in the polymeric body;

a first cover adhered to the first external opposing surface to seal the first flow channels;
a second cover adhered to the second external opposing surface to seal the second flow channels; and
one or more access ports in fluid communication with the continuous 3D flow pathway for introducing liquid reagent(s) and/or a sample into the polymeric body.
