Hydratation of erythrocyte membranes and their interaction with ultrafine silica

V. V. Turov, N. P. Galagan, I. V. Grytsenko, A.A. Chuiko

The interaction of ultrafine silica (UFS) with membrane preparations of donor erythrocytes were investigated by method of ¹Н NMR spectroscopy. The values of their hydratation in contact with silica, interphase energies, concentrations of weakly and strongly bound water were measured and calculated. Possible mechanisms of effect of UFS on cell hemolytic are discussed.

Key words: NMR spectroscopy, ultrafine silica, erythrocytes, membrane, hydratation.
