Abstract

A facile deposition process was developed for the fabrication of a new superhydrophobic layer composed of an underlying zinc oxide nanoparticle support and a gold top layer doped with the hydrophobic chemical, heptadecafluoro-1-decanethiol (HDFT). The resulting microscaled and spherical DNA-based hydrogels could serve as a platform for pseudo-nucleus mimics.

Keywords: DNA nanoarchitecture; DNA-based hydrogel; Heptadecafluoro-1-decanethiol (HDFT); Superhydrophobic; ZnO nanoparticle growth.
