Fig. 3: Microwell size effect on superlattice surface orientation.
From: Macroscale-area patterning of three-dimensional DNA-programmable frameworks
a–d SEM images illustrating DNA origami frame superlattices grown on patterned monofunctionalized Si/SiO2 surface in microwell arrays of 100, 50, and 20 µm, alongside a reference image of a non-patterned area. Blue arrows denote crystals deviating from growing along the <111> direction due to edge effects, pink arrows indicate non-<111> crystals not located at the edges, and green arrows highlight crystals displaying non-<111> due to twinning. e Histogram showing the percentages of superlattice grown along the < 111> direction (as obtained for number crystals, N (for different microwell sizes, a), such as N (20 µm) = 148, N (50 µm) = 648, N (100 µm) = 875, N(nonpatterned) = 2520)) in microwell arrays with different sizes and non-patterned area on monofunctionalized Si/SiO2 surfaces. f Probability of <111> orientation on the inverse of microwell size (1/a). Circles represent experimental data, and a line is a model fit to the data.
