Molecular level nanoelectronics a step closer to reality with DNA nanowire research

19.11.2007
Current voltage characteristics of intrinsic guanine rich DNA sequences

Biological and physical studies on DNA structure have revealed considerable interest into the electronic properties of DNA. Part of this interest is in using DNA as the basis for forming minute nanowires for use in ultra small nanoelectronics.

Molecular nanowires made from DNA can be a building block for the exceptionally small yet powerful computers of the future. An article released as part of the open access journal, AZoJono* takes us a step closer to understanding the electrical properties of DNA with the aim of producing nanoscale devices such as molecular wire.

The research work was conducted by Ram Ajore, Inderpreet Kaur, R.C.Sobti, Lalit M. Bharadwaj of Central Scientific Instruments Organization and Panjab University. Their work found that the conductivity of intrinsic guanine rich sequences of ?-DNA was length dependent. The results of their experiments may provide insights into the electrical behavior of guanine rich sequences with varying intervening bases. It may also be helpful in modifying the conductivity of DNA nanowire.

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...

Im Focus: Tube anemone has the largest animal mitochondrial genome ever sequenced

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....

Im Focus: Tiny light box opens new doors into the nanoworld

Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.

Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
