    • Deposition of materials using DPN is typically a result of their nonspecific physical adsorption to a substrate or the formation of a chemical bond between mercaptans (or disulfides) and a gold substrate. In addition to the work of Frommer and Malkoch (ref 13), other notable exceptions include: (a) Direct deposition of alkoxysilanes onto silicon oxide and silica (see Jung, H.; Kulkarni, R.; Collier, C. P. J. Am. Chem. Soc. 2003, 125, 12096-12097).

    • We observed previously (ref 18) that the performance of catalytically active copper-coated PDMS stamps, used to attach terminal alkynes onto azideterminated surfaces, was sensitive to the elapsed time between (i) copper evaporation onto the stamps and (ii) the use of those stamps for catalytic microcontact printing. Copper stamps that had been aged in air for 24 h were at least 5 times more active than those that were used immediately after copper evaporation.

    • Typical writing speeds using DPN are on the order of 1 μm/s. For a study of writing speed and other parameters on deposition by DPN, see: Weeks, B. L.; Noy, A.; Miller, A. E.; De Yoreo, J. J. Phys. Rev. Lett. 2002, 88, 255505-1-255505-255514
