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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
