Abstract
A microfluidic chip for a microfluidic system includes a PDMS substrate having a first thickness, at least one microfluidic pathway in the substrate, a coating along the microfluidic pathway, and a glass layer having a second thickness on the substrate and above the microfluidic pathway, wherein the coating contains an optically transparent material, and the first thickness is greater than the second thickness. The coating includes cyanoacrylates, an UV curable epoxy adhesive, a gel epoxy or epoxy under trade name of EPO-TEK OG175, MasterBond EP30LV-1 or Locite 0151.
