19. Laser ablation was typically conducted with gold surfaces facing up. Use of an oil immersion lens, therefore, will not contaminate gold films. For a given objective, the diameter of the ablated region can be precisely tuned by adjusting the laser power and/or by defocusing the laser slightly out of the gold plane.

27. Contamination of monolayers previously formed on other elements may occur by displacement of monolayer constituents by alkanethiols in solution. Such cross-contamination may be minimized, however, by using low concentrations of alkanethiols and/or using short immersion times and/or using analogous disulfides. See for example: Biebuyck, H. A.; Bain, C. D.; Whitesides, G. M. Langmuir 1994, 10, 1825.
