Geometry of DNA nanostructures used to program molecular recognition

Adding a new molecular recognition code to structural DNA nanotechnology—a pattern of projecting and recessed blunt-end DNA helices can be used to code the assembly of DNA origami tiles into larger DNA nanostructures.

A modular molecular composite nanosystem for solar power

A bacterial virus called M13 was genetically engineered to control the arrangement of carbon nanotubes, improving solar-cell efficiency by nearly one-third.

New software aids design of 3-D DNA structures

New software for scaffolded DNA origami makes it easier to predict what shape will result from a given DNA template.

DNA nanotechnology builds 3D forms with complex curves (includes video)

The capabilities of scaffolded DNA origami procedures have been expanded to construct arbitrary, two- and three-dimensional shapes.

One-molecule robot to be presented at January's TEDxCaltech conference

A one-molecule robot capable of following a trail of chemical breadcrumbs will be presented at TEDxCaltech-Feynman’s Vision: The Next 50 Years.

Making and opening a Mobius strip with DNA Kirigami

Reconfiguring the topology of DNA nanostructures offers novel architectures for nanodevices.

DNA springs enable mechanical control of enzymatic reaction

DNA springs mechanically control an enzymatic reactions by exerting force on specific parts of the enzyme molecule.

Feynman's Path to Nanotech (part 5)

Is it Worth Starting Now? Surely, you will say, it would have been wonderful if back in 1959 people had taken Feynman seriously and really tried the Feynman path: we’d have the full-fledged paraphernalia of real, live molecular machinery now, with everything ranging from nanofactories to cell-repair machines. After all, it’s been 50 years. The… Continue reading Feynman's Path to Nanotech (part 5)

Advancing nanotechnology by organizing functional components on addressable DNA scaffolds

Two recent publications provide more evidence of the growing capability of DNA scaffolds to support complex and interactive functions.

DNA nanotechnology builds large structures from information-rich seeds

DNA origami structures act as seeds to program the construction of structures up to 100 times larger.
