Bioinspired methodology to fabricate hydrogel spheres for multi-applications using superhydrophobic substrates

Abstract

Inspired by the rolling of water drops over the lotus leaf, we propose a new biomimetic fabrication process for hydrogel and polymeric spheres over a superhydrophobic substrate. This method may be potentially applied in tissue engineering or as support for cell expansion, cell encapsulation and as spherical structures for controlled release of molecule.
