In recent years, scientists have begun to harness DNA's powerful molecular machinery to build artificial structures at the nanoscale using the natural ability of pairs of DNA molecules to assemble into complex structures. Such "DNA origami," first developed at the California Institute of Technology, could provide a means of assembling complex nanostructures such as semiconductor devices, sensors and drug delivery systems, from the bottom up. While most researchers in the field are working...

The enigmatic Möbius strip has long been an object of fascination, appearing in numerous works of art, most famously a woodcut by the Dutchman M.C. Escher, in which a tribe of ants traverses the form's single, never-ending surface. Scientists at the Biodesign Institute at Arizona State University's and Department of Chemistry and Biochemistry, led by Hao Yan and Yan Liu, have now reproduced the shape on a remarkably tiny scale, joining up braid-like segments of DNA to create Möbius...

U.S. nanotechnology scientists say they've developed a technique that allows creation of letters so small that hundreds of thousands could fit into a period. Brigham Young University researchers led by Professor Adam Woolley said development of the new technology helps overcome a long-standing challenge in nanotechnology. The scientists devised ways to fold DNA into nanoscale structures that have multiple branching points. They also describe procedures to form nanostructures of various...

Researchers from Brigham Young University found how to shape customized segments of DNA into tiny letters that spell "BYU." This new method of DNA origami will appear in the aptly titled journal Nano Letters. The letters are about 100 nanometers in size. That's roughly a billion times smaller than the block Y on the mountain overlooking BYU's campus and 1/1000 the width of a human hair. The team's larger pursuit is to design nanoscale shapes for electrical circuitry and make tiny "“ yet...

Scientists at the California Institute of Technology (Caltech) and IBM's Almaden Research Center have developed a new technique to orient and position self-assembled DNA shapes and patterns"”or "DNA origami""”on surfaces that are compatible with today's semiconductor manufacturing equipment. These precisely positioned DNA nanostructures, each no more than one one-thousandth the width of a human hair, can serve as scaffolds or miniature circuit boards for the precise assembly of...

IBM and California Institute of Technology scientists say they have achieved a major breakthrough that might result in smaller, more powerful semiconductors. The researchers said they have used a method called DNA origami to precisely arrange carbon nanotubes, nanowires and quantum dots into tiny structures, thereby producing the equivalent of a DNA circuit board that could form the basis of future computer chips. The inventor of DNA origami, Professor W.K. Rothemund of the California...

By combining the art of origami with nanotechnology, Dana-Farber Cancer Institute researchers have folded sheets of DNA into multilayered objects with dimensions thousands of times smaller than the thickness of a human hair. These tiny structures could be forerunners of custom-made biomedical nanodevices such as "smart" delivery vehicles that would sneak drugs into patients' cells, where they would dump their cargo on a specific molecular target.While creation of structures from single layers...
