1. A method of producing a nanoporous material, comprising:

  • providing a medium into which an amphiphile is dispersed, the medium comprising both solvent and matrix material;

    dispensing the medium onto a substrate;

    removing the solvent, thereby forming a solid structure that comprises the amphiphile dispersed in the matrix material; and

    generating porosity in the matrix material via a templating mechanism by decomposing the amphiphile, thereby leaving porous regions in the matrix material,wherein the amphiphile comprises at least one branched moiety attached to one linear polymeric moiety, wherein the linear polymeric moiety has a degree of polymerization of between 50 and 500, and one of either the branched moiety or the linear polymeric moiety is lyophilic, and the other is lyophobic.
