Gold nanoparticle self-similar chain structure organized by DNA origami.
Here we demonstrate Au nanoparticle self-similar chain structure organized by triangle DNA origami with well-controlled orientation and <10 nm spacing. We show for the first time that a large DNA complex (origami) and multiple AuNP conjugates can be well-assembled and purified with reliable yields. The assembled structure could be used to generate high local-field enhancement. The same method c...
متن کاملDielectrophoresis of gold nanoparticles conjugated to DNA origami structures
DNA nanostructures are promising construction materials to bridge the gap between self-assembly of functional molecules and conventional top-down fabrication methods in nanotechnology. Their positioning onto specific locations of a microstructured substrate is an important task towards this aim. Here we study manipulation and positioning of pristine and of gold nanoparticle-conjugated tubular D...
متن کاملControlled reduction of photobleaching in DNA origami-gold nanoparticle hybrids.
The amount of information obtainable from a fluorescence-based measurement is limited by photobleaching: Irreversible photochemical reactions either render the molecules nonfluorescent or shift their absorption and/or emission spectra outside the working range. Photobleaching is evidenced as a decrease of fluorescence intensity with time, or in the case of single molecule measurements, as an ab...
متن کاملTwo-dimensional DNA origami assemblies using a four-way connector.
Two-dimensional self-assembly of DNA origami structures was carried out using a connector that has connection sites at all four edges. By utilizing this four-way connector, five and eight origami monomers were assembled to form a cruciate and a hollow square structure, respectively.
متن کاملTwo-dimensional DNA origami assemblies using a four-way connectorw
Directionally controlled self-assembly of multiple molecules is an important technique for constructing multidimensional structures. DNA molecules are widely used for controlled self-assembly because of their programmability, defined structure, and acceptance of various functionalizations. The scaffolded DNA origami method developed for the preparation of twodimensional (2D) structures has been...
