demonstrate that this protection–reaction–deprotection sequence
allows the regioselective modification of independently address-
able electrodes on a single substrate.

In summary, we have developed a method that successfully
uses gold oxide as a reversible protecting layer for the directed
self-assembly of monolayers from dihexadecyl disulfide on gold.
This approach is similar to the protection–deprotection scheme
used for analogous reasons in synthetic organic chemistry. The
analogy is not strict, of course, because the electrodes are
independently addressable, and therefore can be selectively
protected or deprotected without relying on inherent differences
in chemical kinetics. Although there are alternative strategies
