On the mechanism of dielectric relaxation in aqueous DNA solutions.

B Saif1, R K Mohr, C J Montrose, T A Litovitz.   

Abstract

The complex dielectric response of calf thymus DNA in aqueous saline solutions has been measured from 1 MHz to 1 GHz. The results are presented in terms of the relaxation of the incremental contributions to the permittivity and conductivity from the condensed counterions surrounding the DNA molecules. Measurements of the low-frequency conductivity of the samples also lends support to the condensed counterion interpretation.
