    • SU8-5 and SU8-50 negative photoresists (Microlithography Chemical Corp., Newton, MA) could be used to span this range of thicknesses. The thickness of the photoresist was measured by profilometry.

    • We found that irreversible sealing between oxidized PDMS surfaces failed if the pieces were not brought into contact within ∼1 min of oxidation. The failure in sealing is presumably caused by adsorption of contaminants from the air or by intrinsic rearrangement of the surface.

    • note
    • We created tightly sealed devices with channels with hydrophobic PDMS (contact angle > 90°) by heating the oxidized PDMS devices in air at 135 °C for 1 h. Morra et al. (ref 75) inferred from the temperature dependence of this change in wetting that it was due to diffusion of polar groups on the surface of oxidized PDMS into the bulk polymer and the condensation of silanol groups; this hypothesis was confirmed by SSIMS and XPS.
