Methods have been developed recently for the preparation of monodisper
se ellipsoidal polystyrene particles which also allow the axial ratio
to be varied. Electrophoretic examination of these particles raised th
e possibility of a nonuniform surface charge distribution. Heterocoagu
lation of small spherical cationic particles onto the surface of the a
nionic ellipsoidal particles has been used to explore this possibility
