Here is an image of a polynorbornene polymer functionalized with 12C-4 ether rings cast into a 90um tall microfluidic device. Both the top and bottom slide of the microfluidic device have a coating of silver creating a reflective cavity. As the solvent evaporates radially outward from the drop of polymer a unique pattern forms within the polymer post.
