12. A microfluidic apparatus, comprising:
-
a first polymeric substrate layer having a plurality of grooves fabricated into a first surface thereof; a second polymeric substrate layer mated with the first surface of the first polymeric substrate layer, the second polymeric substrate layer being bonded to the first surface of the first polymeric substrate layer, thereby defining microscale channel network between the first and second polymeric substrate layers, the microscale channel network falling within an area of the first surface of the first polymeric substrate layer of less than 6 cm2 ; and wherein at least one of the first and second polymeric substrate layers extends disproportionately in one dimension from the an area where the first and second polymeric substrate layers are bonded together in which the microscale channel network falls, to provide a manual handling structure integral to said first or second polymeric substrate layer.
