Surface-bound microgel structures – electrochemical and photochemical synthesis, switching and imaging
 
Project A6 is devoted to the surface-assisted generation of novel switchable microgel (μG) architectures and assemblies. Two approaches are proposed. The first one comprises an electrochemical pathway. Polymer deposition on electrodes will be utilized to replicate the 2D-structure of an electrode into a 3D thin polymer film. After crosslinking, these replicas will be examined for electrochemically-induced actuation. As an alternative, they can be stripped off from the electrode and used as novel anisotropic colloids. The second approach combines chemical e-beam lithography and confocal photolithography for the site-specific immobilization of oligonucleotide (DNA) single strands to nanoscopic spots. This way, targeted assemblies of microgel superstructures can be formed which bring the responsiveness of microgels together with the biomolecular recognition properties of DNA and the thermal addressability of DNA hybridization. The structures and switching properties of microgel assemblies will be visualized using modern fluorescence microscopy techniques.
