Figure 4

Reference experiments with untreated nanowires. In (a) and (b), the dark field and fluorescence image of an unmodified nanowire sample are shown. In (c) and (d), the dark field and fluorescence image of a silanized but not biofunctionalized nanowire sample are shown. In both cases, the fluorescence measurement does not show any sign of distracting fluorescence.
