 | Nanoscience has the potential to play an enormous role in enhancing a range of products, including sensors, photovoltaics and consumer electronics. Scientists in this field have created a multitude of nano scale materials, such as metal nanocrystals, carbon nanotubes and semiconducting nanowires. ...> Full Article |
 | In work that someday may lead to the development of novel types of nanoscale electronic devices, an interdisciplinary team of researchers at the California Institute of Technology has combined DNA's talent for self-assembly with the remarkable electronic properties of carbon nanotubes, thereby suggesting a solution to the long-standing problem of organizing carbon nanotubes into nanoscale electronic circuits. ...> Full Article |
 | DNA origami just got a new "twist" from BYU researchers who use DNA strands of customized length to spell "BYU."The advance puts them one critical step closer to building nanoscale electronic circuits. ...> Full Article |
 | Scientists at the Technische Universitaet Muenchen and Harvard University have thrown the lid off a new toolbox for building nanoscale structures out of DNA, with complex twisting and curving shapes. In the Aug. 7 issue of the journal Science, they report a series of experiments in which they folded DNA, origami-like, into 3-D objects including a beach ball-shaped wireframe capsule just 50 nanometers in diameter. ...> Full Article |

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.

Researchers at Northwestern University in the group of Monica Olvera de la Cruz, professor of materials science and engineering and chemical and biological engineering at the McCormick School of Engineering and Applied Science, have recently shown how electrostatic interactions -- commonly known as static electricity -- alone can give rise to helical shapes. The group has constructed a mathematical model that can capture all possible regular shapes chiral objects could have, and they computed the preferred arrangements induced by electrostatic interactions.

What appear under an atomic force microscope to be tiny rings with little bits missing are actually nanoscopic rings made of double-stranded DNA with a little gap in the form of a short single-stranded fragment. As Michael Famulok and his team from the University of Bonn, Germany, explain in the journal Angewandte Chemie , this gap is a place to attach other molecules that have the potential to transform the rings into versatile nanocomposites for various applications.
