title: A superhydrophobic layer formed by fluoro-derivative-treated gold sheets on grown-up zinc oxide nanoparticles for a spherical DNA hydrogel.
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.
