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.
