Microchip Fabrication. Flowchart of three fabrication methods for the different topographies. The fabrication methods include: two different sizes of wrinkles that generate uniaxial nanoscale channels in the molds, selectively crazed acetone-etched method that generates larger micron-sized channels, and a crazed ‘control’ topography that does not generate uniform channels, but does exhibit random three-dimensional hills, valleys and ridges.
