Abstract：
:Colloidal silical particles were produced at a size that permitted reaction with human erythrocytes and rat macrophages without affecting cell integrity. Binding of colloid was shown by increased electrophoretic mobility of red cells and also resulted in changes in the surface topography of red cells as seen with scanning electron microscopy. The degree to which colloid binds to red cells was determined by microprobe analysis of single intact cells. Furthermore, the capacity of red cells to bind silica was increased if sialic acid residues were removed enzymatically from the cell surface.
