• protocols of particle lithography combined with either vapor deposition, immersion, or contact printing. Changing the physical approaches for applying molecules to masked surfaces produced OTS nanostructures with different shapes and heights. Ring nanostructures, nanodots and uncovered pores of OTS were

• -shaped nanostructures were produced by using latex-particle lithography with immersion, as shown in Figure 5 with wide-area and zoom-in topography views. The long-range periodicity of the array of nanodots is shown with an FFT within the inset of Figure 5a. The surface density of the nanodots is

• approximately 3.3 × 109 nanostructures/cm2, showing ~120 nanopatterns within the 2.5 × 2.5 µm2 frame shown in Figure 5b. The heights of the nanodots measure 0.5 ± 0.3 nm. Immersion of a masked substrate in a solvent is the most common approach for preparing films of OTS, and has produced the most consistent
