    • The permeability of the stamp to ethanol and thiol is readily demonstrated. A drop of a 10 mM solution of HDT in ethanol placed on the free surface of a 1 mm thick PDMS stamp in contact with a gold substrate for 5 min allows sufficient diffusion of HDT through the bulk of the PDMS to protect the gold against an etch in cyanide.

    • 2 and the stamp was further flushed for ≈10 s to remove all visible traces of liquid. Macroscopic quantities of liquid on the stamp were easy to discern as they interfered with conformal contact between the stamp and substrate and generally introduced macroscopic, irregular broadening into the printed pattern.

    • The significance of vapor-phase transport in μCP is well borne out by the following experiment: a cylindrical cavity, 3.5 mm in diameter and 50 μm deep, in PDMS inked for 30 s with a 1 mM solution of dodecanethiol (DDT) in ethanol and placed over a gold substrate spreads enough thiol through the gas phase to form a nearly complete (>90%) protective monolayer of DDT in less than 1 min of exposure (measured by ellipsometry and verified by the etch assay, respectively).

    • Printing DDT at much larger scales can be used to form selective patterns of the molecules on gold although we have found that, even in these cases, a large amount (up to 80% of a monolayer) of DDT adsorbs on the unprinted areas of the substrate.

    • The probability of freezing in gauche conformations in the chain logically increases with molecular weight. Such defects lower the overall order of the film and lead to defects of its barrier properties.

    • We were able to confirm that the behavior of ECT as an ink on this stamp was qualitatively similar to that on replicas for which Sylgard 184 provided the structure.
