Design and construction of a box-shaped 3D-DNA origami.
A box-shaped 3D-DNA origami has been successfully constructed by selective closing of a preformed open motif, and identified by atomic force microscopy and dynamic light scattering analysis.
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 کاملProgrammed placement of gold nanoparticles onto a slit-type DNA origami scaffold.
A novel DNA scaffold, called a DNA slit, was designed for the programmed positioning of Au nanoparticles (AuNPs), and various patterns of thiolated DNA slits were constructed. AuNPs were correctly placed at the predesigned positions in the thiolated DNA slits, indicating that the thiolated staples and the slit cavities guide the correct assembly of AuNPs.
متن کاملConstruction of a recombinant bacmid DNA containing influenza A virus hemagglutinin gene using a site-specific transposition mechanism
Introduction: In recent years, influenza viruses have caused moderate to severe infections all around the world while so far there is no influenza vaccine that can protect people with only one dose of injection. In this regard, producing a universal vaccine based on virus-like-particles (VLP) could be an ideal approach. Methods: In this study, the full-length ORF of influenza hemagglutini...
متن کامل3DNA Printer: A Tool for Automated DNA Origami
In the last two decades, DNA self-assembly has grown into a major area of research attracting people from diverse background. It has numerous potential applications such as targeted drug delivery, artificial photosynthesis etc. In the last decade, another area received wide attention known as DNA origami, where using M13 virus and carefully designed staple strands one can fold the DNA into desi...
