Schematic showing the fabrication of grids with an aperture of 150 µm for crystal wells and 30 µm for wicking holes using NOA. (a) Negative PDMS master is fabricated by micro molding off SU-8. (b) The PDMS master is used to imprint the design into NOA 68 T using both (i) batch and (ii) continuous roll-to-roll processing.
