Claim Text:
1. A microfluidic workpiece, comprising: a microfluidic channel being impressed in the surface of a thermoplastic substrate, the microfluidic channel defining a depth and the microfluidic channel comprising a characteristic dimension in the range of from about 0.5 micrometers to about 100 micrometers, the microfluidic channel being adjacent to at least one secondary region, the secondary region defining a depth that is less than the depth of the microfluidic channel; a wall defining a boundary between the microfluidic channel and the secondary region; and at least one probe residing on a surface of the microfluidic channel; a radiation-absorbing compound residing in the secondary region, wherein the wall separates the radiation-absorbing compound from the microfluidic channel; and a thermoplastic member that is disposed above and opposite to the thermoplastic substrate and that at least partially overlaps the microfluidic channel of the thermoplastic substrate, the thermoplastic member being bonded to the thermoplastic substrate at the location of the radiation-absorbing compound.
