  • Title: On the mechanism of dielectric relaxation in aqueous DNA solutions.
    Author: Saif B, Mohr RK, Montrose CJ, Litovitz TA.
    Journal: Biopolymers; 1991 Sep; 31(10):1171-80. PubMed ID: 1790296.
    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.
