    • We could not elucidate the phase behavior of MHA and ODT on the molecular level. Several studies based on scanning tunneling microscopy suggest that nanometer-scale domains may form when alkanethiols co-adsorb from a solution onto a gold substrate. See, for example: S. J. Stranick, S. V. Atre, A. N. Parikh, M. C. Wood, D. L. Allara, N. Winograd, P. S. Weiss, Nanotechnology 1996, 7, 438-442.

    • More recently, Mirkin and coworkers reported the near-complete phase-separation of MHA and ODT in mixed SAMs that were patterned by dip-pen nanolithography. See: K. Salaita, A. Amarnath, D. Maspoch, T. B. Hig gins, C. A. Mirkin, J. Am. Chem. Soc. 2005, 127, 11283-11 287. We do not think that the findings of these authors are necessarily contradictory to ours as the transport mechanisms for the thiol molecules are somewhat different in these two methods.

    • note
    • We performed our experiments in a clean room (class 1000) with semi-controlled temperature (19±1°C) and humidity (50 ± 10%). However, the width of individual rings was prone to variation, as indicated by the relatively large error bars in the graph. In most cases, the ring width varied from one region to another on the same substrate, but was typically uniform within arrays. We believe that local variations in the population of beads on the gold substrate in conjunction with inking and printing artifacts primarily account for this finding.
