Do-It-Yourself DNA nanotechnology from Caltech

Kevin Bullis reports in Technology Review: Now Paul Rothemund, a computer scientist at Caltech, with a background in biology, has developed a relatively inexpensive way to quickly design and build arbitrary shapes and patterns using DNA — and, he says, it’s simple enough for high-school students to use… It’s really spectacular work. I’m extremely excited about… Continue reading Do-It-Yourself DNA nanotechnology from Caltech

A DNA nanotechnology road to molecular assembly lines?

A piece in The Christian Science Monitor compares Nadrian Seeman, founder of the field of structural DNA nanotechnology and winner of the 1995 Foresight Feynman Prize in Nanotechnology, with Henry Ford—implying that his recent accomplishment with his collaborators in creating a two-armed DNA nanorobot could point to a role for DNA nanorobots in future nanotech… Continue reading A DNA nanotechnology road to molecular assembly lines?

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.

Structural DNA nanotechnology arrays devices to capture molecular building blocks

Two independently controlled nanomechanical devices can be positioned on a two-dimensional DNA grid so that they can cooperate to capture between them one of four DNA building blocks, determined by which of two possible states each device is set to.

Combining structural DNA nanotechnology and gold nanoparticles to make decorated DNA nanotubes

Researchers have been able to attach gold nanoparticles to DNA tiles and, by varying the size of the nanoparticles and the presence of DNA stem loops on some tiles, have been able to control the formation from the DNA tiles of various three dimensional DNA nanotubes.

DNA nanotechnology provides an improved tweezers

Re-engineering a simple nanotech device to make it more functional, Chinese scientists have developed an improved DNA tweezers that is able to capture, hold, and release a target molecule in a controlled manner.

Structural DNA nanotechnology in living cells

Two basic structural motifs of DNA nanotechnology have been efficiently and inexpensively replicated in bacterial cells.

A new glycerol nucleic acid (GNA) building block for structural DNA nanotechnology

A new building block for structural DNA nanotechnology uses a 3-carbon glycerol molecule instead of the 5-carbon sugar deoxyribose found in DNA.

Structural DNA nanotechnology builds dodecahedron from three-legged building blocks

Three short DNA strands attached to one aromatic ring containing six carbon atoms form three-legged building blocks that assemble into a dodecahedron.

Founder of structural DNA nanotechnology field awarded medal by American Chemical Society

The American Chemical Society has awarded Nadrian Seeman its Nichols Medal for establishing the field of structural DNA nanotechnology, nearly 13 years after the Foresight Institute awarded Seeman the 1995 Feynman Prize in Nanotechnology.
