title: One-pot microfluidic fabrication of graphene oxide-patched hollow hydrogel microcapsules with remarkable shell impermeability.
abstract: Uniform hollow hydrogel microcapsules, composed of a graphene oxide platelet-patched shell, are fabricated in one step in a capillary-based microfluidic device. We demonstrate that patching a small amount of graphene oxide at the interfaces remarkably prevents the leakage of small molecules through the shell.
