Neutralized DNA gels exhibit a reversible volume transition when CaCl2 is added to the surrounding aqueous NaCl solution. In this paper, a systematic study of the osmotic and mechanical properties of Na-DNA gels is presented to determine, qualitatively and quantitatively, the effect of Ca-Na exchange on the volume transition. It is found that in the absence of CaCl2 the DNA gels exhibit osmotic behavior similar to that of DNA solutions with reduced DNA concentration. At low CaCl2 concentration… CONTINUE READING
