| Abstract: | The methods for determination of Zeta potential were introduced and concluded according to the literatures, and its application in the study of pharmaceutical dispersion systems were reviewed also. The most common methods for determining the zeta potential are the microelectrophoresis, electrophoretic light - scattering, and electrokinetic sonic analysis. Zeta - potential measurement has played an important role in the research of pharmaceutical emulsions, suspensions, and liposomes, it has been recognized as an excellent tool for characterizing physical stability of pharmaceutical dispersion systems. |
