In thisĬase, the topology of the two connected scaffold strands is such thatĭecatenation can be achieved without covalent bond breaking. Mobius strip followed by removal of selected staple strands. 35 This was achieved by splitting a DNA origami In 2010 when a two-ring DNA origami catenane was produced. Very few examples of topologically linked DNA origami structures Machines with increased functionality and sophistication due to theĪbility to irreversibly link together discrete DNA origami structures. As a result, it has the potential to construct molecular Greater structural redundancy compared to classical topologically Generated a range of catenated products, and has not been appliedĪn attractive goal due to its high molecular weight and resulting 34 However, this approach showed poor efficiency, In a study, which used Ena/Vasp-like protein and topoisomerase I. SsDNA circles of a length suitable for DNA origami has been demonstrated Production of considerably longer catenated 28, 33 However, this approach results in small (sub-200 nt) catenanes,Įssentially an order of magnitude smaller than required to make complexĭNA origami structures. 31 The resulting structures have been shown capable of functioningĪs switches 27, 32 and rotary motors. They involve enzymatic ligation or chemical coupling of short linearĭNA components following geometric prearrangement by DNA origami, 26 hybridization of short complementary sequences 27− 30 or conjugation with dsDNA-binding moieties. In recent years, catenated ssDNA rings haveīeen designed and produced in vitro using a number of methods. Topologically linked DNA molecules are known to occur in nature 25 and are also attractive as artificial constructs Included hybridization of sticky ends 19 or base stacking 7, 20− 22 and have achievedĪddressable semimicrometer-scale tiles. 15− 18 Efforts to connect together discrete DNA origami structures have Have been reported, including those that are shortened, 10, 11 extended, 12− 14 or otherwise modified to provide arbitrary lengthĪnd sequences. 8, 9 While customization of scaffolds can be challenging, numerous examples Whose opening can be programmed in response to stimuli. Strand is thousands of bases long, providing enough material for theĬonstruction of complex, rigid structures such as dynamic containers “staple” strands, which bind to cognate sequences distributed 5ĭNA origami is a DNA nanotechnology in which a long single-strandedĭNA “scaffold” is shaped by the action of many short Liquid crystals, and other new materials. In 1983 2, 3 with Stoddart demonstrating a rotaxane almostīeen many examples of topological molecules, 1 and demonstrated applications include nanometric electronic switches, 1 They achieved particular prominence after Sauvage’sĭemonstration of the templated approach to molecular catenane synthesis Whatever you decide to do with them I’m sure you’re going to love them.Molecules such as catenanes and rotaxanesĪre challenging and fascinating targets in supramolecular chemistry. Hang them on the tree as Christmas decorations or string them up as a garland. They look fantastic against plain brown paper wrapping. ![]() There are so many different ways you could use these cute origami bows. If you’re looking for an easier origami bow? Make sure to check out my Easy Origami Bow Ties. As they involve a couple of cuts this makes them technically kirigami, not origami, but don’t let that put you off. There's no glue needed although you do need to make a couple of cuts with a pair of scissors. They make the perfect gift topper or garland. ![]() They’re a really cute little bow that you can use to decorate your DIY gift boxes. Want to know how to make a simple paper bow? Then these DIY origami bows are the answer. This means that if you make a purchase after clicking a link I earn a small commission but it doesn’t cost you a penny extra! Origami Bow.
