Functionalised macroporous scaffolds have been fabricated by a decoupled two-step approach comprising plasmachemical deposition of the host material followed by spontaneous emulsion formation using templating molecules. This unique approach allows pore architecture and surface functionalisation to be tailored independently. Other key features encompass conformality to a range of substrate materials or geometries, and the scope for introduction of a wide variety of pore surface functionalities, which for instance include pore size actuation.
