A Close Look at Proteins: Submolecular Resolution of Two- and Three-Dimensionally Folded Cytochrome c at Surfaces

Klaus Kern, Stephan Rauschenbach, Gordon Rinke, Nicha Thontasen

Imaging of individual protein molecules at the single amino acid level has so far not been possible due to the incompatibility of proteins with the vacuum environment necessary for high-resolution scanning probe microscopy. Here we demonstrate electrospray ...

The Quantum Magnetism of Individual Manganese-12-Acetate Molecular Magnets Anchored at Surfaces

Klaus Kern, Markus Ternes, Stephan Rauschenbach, Gordon Rinke, Nicha Thontasen

The high intrinsic spin and long spin relaxation time of manganese-12-acetate (Mn-12) makes it an archetypical single molecular magnet. While these characteristics have been measured on bulk samples, questions remain whether the magnetic properties replica ...

Grafting Crown Ether Alkali Host-Guest Complexes at Surfaces by Electrospray Ion Beam Deposition

Klaus Kern, Stephan Rauschenbach, Nicha Thontasen

The functionalization of surfaces with host guest compounds is promising for many applications, yet often limited by constraints such as the volatility of the functional compound or the lack of binding to the surface. We use electrospray ion beam depositio ...

Electrospray Ion Beam Deposition: Soft-Landing and Fragmentation of Functional Molecules at Solid Surfaces

Klaus Kern, Stephan Rauschenbach, Giovanni Costantini, Nicha Thontasen

The ion, beam deposition (IBD) of rhodamine dye molecules on solid surfaces in high vacuum is explored in order to characterize the possibility of fabricating molecular coatings or nanostructures from nonvolatile molecules. Molecular ion beams with a well- ...
