Abstract

original image

Various hydrophobic hairy carbonaceous fibers are obtained by a low-temperature CVD process on catalyst-patterned surface patches which are selectively coated with silica to make the surface superhydrophobic and yet allow strong water adhesion for the “Salvinia effect”. The versatility of the functional hairy fiber surfaces is demonstrated with a liquid barrier grid for cell microarray, a gas retaining capability under water/liquid for a membrane-free microfluidic chemical process, and functionalized papillae for cell immobilization with green algae.
