The fuzzy line between biology and materials science: Using DNA to build new materials

By Eileen De Guire / October 18, 2011

NYU scientists have developed artificial structures consisting of triple helix molecules containing three DNA double helices that can self-replicate. In the above illustration, two BTX domains are paired by two lateral connections (another two existing connections are not shown). The cross-section view shows two of the four helices that are formed by the lateral cohesive…

Nanodiamonds move into gene therapy

By / September 2, 2009

A team of Northwestern University researchers has figured out a way to use nanodiamonds to deliver DNA for gene-therapy application. By modifying the surface of nanodiamond particles with a special polymer, a group led by Dean Ho found they could reach a delivery efficiency that is 70 times greater than that of a conventional standard…

The world’s first controllable molecular gear

By / June 19, 2009

Researchers in Singapore have advanced the science of nanotechnology by becoming the first in the world to invent a molecular gear of only 1.2 nm in size whose rotation can be deliberately controlled. This achievement was published on June 14 in Nature Materials. The gear is made of carbon compounds and can freely rotate around…
