Fecha de publicación: | oct-2007 | Editor: | Taylor & Francis | Citación: | Nucleosides, Nucleotides and Nucleic Acids | Resumen: | Several linear and branched DNA structures from 80-200 nm with a biotine molecule in the middle have been prepared. These structures have been decorated by addition of positively charged gold nanoparticles carrying 4-(dimethylamino)pyridine ligands. Streptavidin binds to the central biotine molecule introducing a 20 nm gap in the structure in which a biotinylated nanoparticle can be introduced. The simplest structure (80 nm, linear) is formed by 4 oligonucleotides. By changing some of these components changes on length, shape, and recognition system easily can be introduced. | Versión del editor: | DOI: 10.1080/15257770701548675 | URI: | http://hdl.handle.net/10261/124965 | DOI: | 10.1080/15257770701548675 |
