    • Indeed, when the metal thiolation step in the functionalization process was performed after the PEG-silane step, we observed that the biotin-thiols physisorbed on the PEG surrounding the nanodots and functioned as anchoring points for streptavidin and consequently for the DNAs, thus increasing the background fluorescence and preventing the resolution of single nanodots via epifluorescence microscopy imaging

    • Photobleaching occurred at a rate that was more than 1 order of magnitude lower than the rate of PvuII cleavage (Figure SI-5). This allowed us confidently to dismiss photobleaching in our single-molecule enzyme data.

    • This was done by counting the number of discrete steplike drops in the fluorescence intensity versus time for trajectories arising from both PvuII activity (on PvuII-treated nanoarrays) and photobleaching (on untreated nanoarrays).

    • The remaining ∼15% of the nanodots lacked discrete steplike drops in fluorescence intensity and instead exhibited a relatively continuous decay likely arising from a large density of immobilized DNAs, thus preventing single-molecule resolution.
