Abstract

Using microwave dielectric spectroscopy, we have recently shown a new category of water molecules, hyper-mobile water, around actin filaments and chaotropic ions which have much higher mobility than that of bulk water. The purpose of this study is to solve the formation mechanism of hyper-mobile state of water. By our rough estimation, the strength of the electric field around those solutes was found to be in the range of 107-108 V/m indicating that the electric field is one of the important factors for induction of hyper-mobile state of water. On the basis of this hypothesis, we measured poly(x,x-ionene)s which charge density was controlled.The results showed that (2,2)- and (3,3)-ionenes formed the hyper-mobile water, while (4,4)-,(6,6)-ionenes did not. The strength of electric field of (2,2)-(3,3)-ionens were estimated to be 4*107-1*10 8 V/m that were in the range as noted above.
