A detailed understanding of the binding properties of DNA to different transparent surfaces is prerequisite for these investigations. Atomic force spectroscopy and fluorescence microscopy of single DNA strands yielded detailed insight into two different types of DNA binding onto transparent polylysine-coated and silanized glass surfaces. We subsequently demonstrate how the different binding can be exploited to perform two types of nanomanipulation experiments: On polylysine, strong electrostatic interactions over the whole length of the DNA strand enable the writing of micrometer-sized patterns. By contrast, the strong pointwise attachment of DNA to silanized surfaces allows horizontal stretching of single DNA strands to lengths exceeding 1.6 times the contour length of the DNA strand. With this new approach it is possible to directly observe the rupture of the strongly bonded DNA strand.</dcterms:abstract> <dc:contributor>Bräuchle, Christoph</dc:contributor> <dc:language>eng</dc:language> <dcterms:issued>2005-03</dcterms:issued> <dc:contributor>Zhou, Chunqing</dc:contributor> </rdf:Description> </rdf:RDF>
