| This presentation deals with the use of different interfaces guiding the self-assembly of various soft colloidal particles [1]. First, we describe classical oil/water emulsion systems, the so-called Pickering emulsions. Here, the controlled assembly of protein-polymer conjugate nanoparticles (Ferritin-PNIPAAm) followed by crosslinking the polymer matrix leads to permeable, yet highly flexible and stable membranes and capsules [2,3].
Moreover, we demonstrate that nanostructured substrates produced from wrinkling instabilities with wavelengths on the order of only a few hundred nanometers, effectively guide the self-assembly of various well-defined organic nanoparticles (e.g. proteins or microgels) [4, 5]. This process allows the creation of anisotropic large scale particle arrays and supramolecular constructs like composite particulate nanoscale fibres.
