Optimized assembly and covalent coupling of single-molecule DNA origami nanoarrays.
Artificial DNA nanostructures, such as DNA origami, have great potential as templates for the bottom-up fabrication of both biological and nonbiological nanodevices at a resolution unachievable by conventional top-down approaches. However, because origami are synthesized in solution, origami-templated devices cannot easily be studied or integrated into larger on-chip architectures. Electrostati...
متن کاملDNA origami: the art of folding DNA.
The advent of DNA origami technology greatly simplified the design and construction of nanometer-sized DNA objects. The self-assembly of a DNA-origami structure is a straightforward process in which a long single-stranded scaffold (often from the phage M13mp18) is folded into basically any desired shape with the help of a multitude of short helper strands. This approach enables the ready genera...
متن کاملUnscheduled DNA synthesis in cell lysate system reflecting DNA repair in vivo.
A cell lysate system by which DNA repair (unscheduled) synthesis induced by DNA damaging agents can be measured at high sensitivity as previously reported (9, 18) was characterized. Time-course experiments in which the in vivo incubation time with hydroxyurea and arabinofuranosyl cytosine after UV irradiation was changed suggested that the number of single strand gaps increased in the presence ...
متن کاملDielectrophoretic trapping of multilayer DNA origami nanostructures and DNA origami-induced local destruction of silicon dioxide.
DNA origami is a widely used method for fabrication of custom-shaped nanostructures. However, to utilize such structures, one needs to controllably position them on nanoscale. Here we demonstrate how different types of 3D scaffolded multilayer origamis can be accurately anchored to lithographically fabricated nanoelectrodes on a silicon dioxide substrate by DEP. Straight brick-like origami stru...
