Contact potential difference of cells in vitro as a measure of hydrophilic properties of the cell membrane.
Construction of an apparatus for the determination of the cell contact potential difference and the measuring method are described. The contact potential differences are attributed to the degree of hydrophobic properties of the cell surface and referred to human erythrocytes and chloroplasts.
