Self-assembling nanostructures of DNA — a biotechnologist's dream

05.02.2007
Wouldn't it be great if we could get computer chips to grow on trees? Or at least use the specific bonds of DNA molecules to get nanostructures to grow themselves right in the test tube? This technology could be used to build everything from tiny electronics components to machines that sequence DNA. This is shown in a dissertation from Mid Sweden University.

Building structures as tiny as a few nanometers is a major problem with today's technology. This is an important hurdle, because really tiny things can be extremely useful. Good examples are microelectronics, the smaller you can make the components on a chip, the faster you will be able to carry out calculations on it.

"The method we have developed for self-assembling blocks of DNA and gold particles is absolutely unique. The method can be used, for instance, to produce tiny nano carriers for drugs that can be emptied directly in cells on a given chemical signal," says Björn Högberg.

Björn Högberg has also taken a close look at a method for building nanostructures with the help of DNA that was invented by a a US researcher in the spring of 2006. The method is called 'DNA origami' and involves, in brief, folding or splicing together a long string of DNA with the aid of a large number of short strings ('staple DNA').

"In my dissertation I propose just how this technology could be used to construct a facility for extremely rapid DNA sequencing, which is a biotechnologist's dream," says Björn Högberg.

The title of the dissertation is DNA-Mediated Self-Assembly of Nanostructures-Theory and Experiments.

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Im Focus: Carbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects

A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
