Water-soluble proteins to be investigated require Polyhistidine-tags, allowing the macromolecule to be anchored to a lipid bilayer, which is attached to a Germanium crystal or other suitable optical media.
Her website also has crystals that have been laser etched with three-dimensional patterns, including models of nearby stars, the DNA macromolecule, and the Milky Way Galaxy.
His field of research is the physics of soft matter, the physics of coulomb fluids and macromolecular interactions, the Lifshitz theory of dispersion interaction, the physics of membranes, polymers and polyelectrolytes and especially the physics of DNA and viruses.
