Schematic presentation of the fabrication steps of the thiol-ene micropillar arrays: (a) SU-8 master fabrication in cleanroom, (b) PDMS soft lithography at 80 °C for 3 h, (c) thiol-ene replica-molding: removal of trapped air in vacuum followed by UV curing, and (d) lamination and bonding of the cured thiol-ene layers under UV for 2 min. (e) SEM images of the IMER’s inlet side with triangular opening not containing micropillars (left) with close-up views to the ordered micropillar arrays (middle and right)
