Optimization of TiO2/quartz surface preparation for single-molecule imaging. (a) Distribution of fluorescent intensity from individual PS particle adsorbed on bare quartz (black, molecule n = 1194), 1 nm (red, molecule n = 1256), and 5 nm coating (blue, molecule n = 39) of TiO2. (b) Fluorescent intensity distribution from individual Cy3-Oligo-DNA adsorbed on bare quartz (red, molecule n = 1688) and 1 nm Ti (black, molecule n = 759).
