Current voltage characteristics of intrinsic guanine rich λ-DNA sequences
(2007) In Azojono- Abstract
- In the present manuscript, current-voltage (I-V) measurements of double stranded guanine rich sequences of λ-DNA have been reported. These sequences show length dependent conductivity. Conductivity (σ0) DNA of length, L = 0.6494 x 10-4 (1910 bp), 1 x 10-4 (2947 bp) and 1.3498 x 10-4 cm (3970 bp) was found to be 2.4 x 105, 7.7 x 102 Ω-1cm-1 and insulator behavior, respectively. I-V characterization of immobilized DNA was done on gold micro-electrodes fabricated by laser ablation using Optical Tweezer of power 0.66 mW. Charge transfer distance evaluation of intrinsic guanine rich sequences show increasing frequency of intervening bases between conducting units with increase in length. Outcomes of the present study can be useful for... (More)

Outcomes of the present study can be useful for ascertaining the behavior of nanowires with varying charge transfer distance (Less)
