Brief Bio of the Speaker

Harald Fuchs is a Full-Professor of Experimental Physics at the University of M┨nster, Germany. He received his PhD degree in 1982 at the University des Saarlandes, Saarbr┨cken and spent from 1984 C1985 a post-doctoral year with IBM Research Laboratory Zurich in the group of G. Binnig & H. Rohrer. From 1985-1993 he was heading the ?Ultrathin Organic Films¨ project with BASF AG, Germany, before he became in 1993 a Full Professor and Director of the Physical Institute of the University of M┨nster. He is the founder of the Center for nanotechnology (CeNTech) in M┨nster and its scientific director since 1993. He is also leading a nano-bio research project at the institute of nanotechnology (INT) at the Karlsruhe Institute of technology (KIT). His research focuses on nanoscale science and nanotechnology, ranging from scanning probe microscopy to self-organized nanostructure fabrication, and nano-bio systems. He has published more than 450 scientific articles, and has filed more than 30 patents. He was awarded several research prizes, including the Philip Morris Prize. He holds 3 guest professorships in Asia. He is a cofounder of several nanotechnology companies and a member of the Editorial Boards in several international journals. Since 2008 he has been the German spokesperson of the first SinoCGerman DFG/NSFC collaborative project SFB/TRR61. He is an elected member of the German National Academy of Science `Leopoldina¨, the German National Academy of Science and Engineering 'acatech', and the 'TWAS'.

Abstract

The formation of chemical bonds depends strongly on the spatio-temporal conditions within an ensemble of starting molecules. We found that by using nanostructured surfaces on metallic single crystals, a significant increase of the reaction rate can be obtained, even with simple linear hydrocarbons exhibiting very poor chemical reactivity. By imposing appropriate self-organized nano-confinements on the metallic surface which promote heterogeneous catalysis, polymerization of the linear monomeric units at mild conditions is obtained via CH-activation. The concept can be extended to 2-dimensional Glaser-coupling reactions on low indexed surfaces. The examples presented demonstrate new pathways to generate specific chemical bond formation which is unlikely to occur with conventional chemical techniques. In the second part of the talk a novel approach for preparing a multimode near field optical probe the generation of biomimetic systems using Dip Pen Nanolithography (DPN) will be discussed. The latter allows us to write chemical diverse small structures for the interaction with biological systems such as biological cells. Recent developments and perspectives for the generation of biomimetic surfaces and sensor applications will be presented.
