1. A microfluidic device, comprising:

  • a first polymeric substrate comprising a first planar surface having a plurality of microscale channels disposed therein;

    a second polymeric substrate comprising a first planar surface, the first planar surface of the second substrate being non-solvent bonded to the first planar surface of the first substrate, wherein the first surface of the second substrate does not substantially project into the plurality of channels and wherein the first and second substrates comprise polymethylmethacrylate, and said first substrate has a different transition temperature than said second substrate.
