Controlling DNA Bundle Size and Spatial Arrangement in Selfassembled Arrays on Superhydrophobic Surface

The use of superhydrophobic surfaces (SHSs) is now emerging as an attractive platform for the realization of\r\none-dimensional (1D) nanostructures with potential applications in many nanotechnological and biotechnological fields.\r\nTo this purpose, a strict control of the nanostructures size and their spatial arrangement is highly required. However, these\r\nparameters may be strongly dependent on the complex evaporation dynamics of the sessile droplet on the SHS. In this\r\nwork, we investigated the effect of the evaporation dynamics on the size and the spatial arrangement of self-assembled 1D\r\nDNA bundles. Our results reveal that different arrangements and bundle size distributions may occur depending on droplet\r\nevaporation stage. These results contribute to elucidate the formation mechanism of 1D nanostructures on SHSs.
