Research Interests

Field of Expertise & Research Interests: Polymer Science as a Bridge between Material Science and Life Science.

Molecular Architecture and Functionalization of Polymeric Liquid Crystals: Synthesis, structure and property of liquid crystalline side group and main chain polymers; variation of the type of mesogens (rods, discs, boards) and variation of phases. Dye containing and photoreactive liquid crystalline polymers for reversible information storage and non linear optic materials. Phase induction and phase variation of liquid crystalline systems via Charge-Transfer-interaction and metal complexation. Photoconductive discotic systems.

Synthesis, Structure and Properties of Functional Supramolecular Systems: Polymerizable and functional amphiphiles (detergents, lipids), polymeric monolayers and multilayers via the Langmuir-Blodgett technique and via self-assembly on various surfaces. Liposomes, Black Lipid Membranes, mobile supported bilayers, H-bond induced band structures in water, organization and recognition induced functionality. Multicompartment polymer micelles.

Attempts to Mimic Biomembrane Processes: Synthetic and natural receptors in molecular assemblies; molecular recognition, 2D-crystallization and function of proteins on monolayers and liposomes, e.g. lectins, streptavidin, monoclonal antibodies, phospholipase A2 and acetylcholinesterase, tailoring of bioreactive surfaces; mixed protein multilayers. Protein–DNA-interaction at ligand lipid monolayers.

Polymers as Active Agents in the Medical Field: Polymer Therapeutics, Polymer radiation prophylactics, polymeric antitumour agents on a molecular and a cellular level.

Famous quotes containing the words interests and/or research:

    I confess what chiefly interests me, in the annals of that war, is the grandeur of spirit exhibited by a few of the Indian chiefs. A nameless Wampanoag who was put to death by the Mohicans, after cruel tortures, was asked by his butchers, during the torture, how he liked the war?—he said, “he found it as sweet as sugar was to Englishmen.”
    Ralph Waldo Emerson (1803–1882)

    The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?” [Was will das Weib?]
    Sigmund Freud (1856–1939)
