I am interested in the image clarity that your chips can provide. Fabrication of complex microfluidic device can be tedious and expensive, but a 3D printer would drastically reduce the cost and increase the reproducibility. However, I am not sure that the 3D printed materials are clear enough to have good image clarity.  Do you have any 3D printed chips that have been imaged using fluorescence? Can I please get a sample of your most optically clear material?
