THE EFFECT OF CATIONIC ELECTROLYTES ON THE ADHESION OF CELLS

The adhesion rate of cells under charge regulation onto a spherical co llector with constant potential is investigated in this paper. Particu larly, the effect of the presence of cationic electrolytes in the susp ension medium on the adhesion rate is examined.The result reveals that the presence of cationic electrolytes in the suspension medium raises the electrostatic repulsion force between cell and collector surface, when the separation distance between them is small than a critical va lue. This has the effect of decreasing the adhesion rate of cells. The adhesion rate of cells is quite sensitive to the value of Hamaker con stant, especially at a high ionic strength value.
